changing systems, forming a complex mixture of many different habitat types. They are very productive biomes and support many important ecosystem functions: biogeochemical cycling and movement of nutrients, mitigation of floods, maintenance of biodiversity and biological production. Human pressure on estuaries is very high. On the other hand, it is recognized that estuaries have a unique functional and structural biodiversity. Therefore, these ecosystems are particularly important for integrating sound ecological management with sustainable economics. These opportunities are explored for the Scheldt estuary, a well-documented system with an exceptional tidal freshwater area. In this article a description of the Scheldt estuary is presented, illustrating that human influence is intertwined with natural dynamics. Hydrology, geomorphology, trophic status and diversity are discussed, and possible future trends in both natural evolution and management are argued.</span></div><div class="wp-workCard_item"><div class="carousel-container carousel-container--sm" id="profile-work-99924468-figures"><div class="prev-slide-container js-prev-button-container"><button aria-label="Previous" class="carousel-navigation-button js-profile-work-99924468-figures-prev"><span class="material-symbols-outlined" style="font-size: 24px" translate="no">arrow_back_ios</span></button></div><div class="slides-container js-slides-container"><figure class="figure-slide-container"><a href="https://www.academia.edu/figures/53325021/figure-1-map-of-the-scheldt-estuary"><img alt="Figure 1.

Evolution of mean high water level (MHW, squares) and mean low water level (MLW, open circles) in the Scheldt estuary near Antwerpen (based on data of the Maritime Access Division of the Flemish Government). Intertidal habitat was also lost due to dike building. In order to protect the land against storm floods from the North Sea all dikes along the estuary (more than 700 km) have been heightened and strengthened. Therefore, the base of the dikes needed to be widened, which was mostly done on the marshes and not on the landside of the dike. By now, over more than 50% of the total length of the estuary lacks tidal marshes in front of the dike. This disrupted the connectivity of marshes along the salinity gradient.

The dis- tribution of suspended matter is influenced by a range of interrelated processes (e.g. temperature and biological activity, fresh water discharge and salinity, hydrodynamic conditions and turbulence, mineralogical composition, chemical conditions, aggregation and flocculation). In the Scheldt estuary, the turbidity maximum is situated at about 110 km from the mouth during dry periods and at about 50 km during wet periods (Wollast, 1988). Two MTZ might be observed, one at the freshwater/seawater interface, and a second one originating from tidal asymmetry (Baeyens et al., 1998; Fettweis et al., 1998; Herman & Heip, 1999).

They are very productive biomes and support many important ecosystem functions: biogeochemical cycling and movement of nutrients, mitigation of floods, maintenance of biodiversity and biological production. Human pressure on estuaries is very high. On the other hand, it is recognized that estuaries have a unique functional and structural biodiversity. Therefore, these ecosystems are particularly important for integrating sound ecological management with sustainable economics. These opportunities are explored for the Scheldt estuary, a well-documented system with an exceptional tidal freshwater area. In this article a description of the Scheldt estuary is presented, illustrating that human influence is intertwined with natural dynamics.

Nevertheless, insitu observations of storm surge attenuation within wetlands are still scarce. We present water level measurements along a 4 km intertidal channel and on the surrounding marsh platform for regular spring to neap tides and two major storm surge tides, showing the effects of flood wave height and marsh geomorphology on the amount of flood wave attenuation. Undermarsh tides with peak water levels below marsh platform elevation are mostly amplified (up to 4 cm/km) within the channels. Overmarsh tides with peak water levels above the marsh platform are generally attenuated along the channels, with maximum attenuation rates of 5 cm/km for tides that inundate the marsh platform by 0.5-1.0 m. For lower or higher flood waves, including storm surges, attenuation rates decrease. Furthermore, the observations show that the maximum attenuation occurs along narrow channel transects where the width of the platform is larger, whereas attenuation rates are lower along wider channels with smaller adjacent marsh platforms. These observations are confirmed by an analytical approximation of tidal wave propagation through convergent channels. The analytical model indicates that differences in attenuation rates are induced by variations in the cross-channel averaged friction between channel sections and between tides with varying peak water levels. Finally, the highest attenuation rates of up to 70 cm/km are observed over short distances on the vegetated marsh platform. We conclude that this 2 study provides an empirical basis for the wider implementation of nature-based flood defense 18 strategies.</span></div><div class="wp-workCard_item"><div class="carousel-container carousel-container--sm" id="profile-work-95887013-figures"><div class="prev-slide-container js-prev-button-container"><button aria-label="Previous" class="carousel-navigation-button js-profile-work-95887013-figures-prev"><span class="material-symbols-outlined" style="font-size: 24px" translate="no">arrow_back_ios</span></button></div><div class="slides-container js-slides-container"><figure class="figure-slide-container"><a href="https://www.academia.edu/figures/25754256/figure-1-observations-of-tidal-and-storm-surge-attenuation"><img alt="" class="figure-slide-image" src="https://figures.academia-assets.com/97942111/figure_001.jpg" /></a></figure><figure class="figure-slide-container"><a href="https://www.academia.edu/figures/25754263/figure-2-observations-of-tidal-and-storm-surge-attenuation"><img alt="" class="figure-slide-image" src="https://figures.academia-assets.com/97942111/figure_002.jpg" /></a></figure><figure class="figure-slide-container"><a href="https://www.academia.edu/figures/25754269/figure-3-observations-of-tidal-and-storm-surge-attenuation"><img alt="" class="figure-slide-image" src="https://figures.academia-assets.com/97942111/figure_003.jpg" /></a></figure><figure class="figure-slide-container"><a href="https://www.academia.edu/figures/25754273/figure-4-observations-of-tidal-and-storm-surge-attenuation"><img alt="" class="figure-slide-image" src="https://figures.academia-assets.com/97942111/figure_004.jpg" /></a></figure><figure class="figure-slide-container"><a href="https://www.academia.edu/figures/25754277/figure-5-observations-of-tidal-and-storm-surge-attenuation"><img alt="" class="figure-slide-image" src="https://figures.academia-assets.com/97942111/figure_005.jpg" /></a></figure><figure class="figure-slide-container"><a href="https://www.academia.edu/figures/25754284/figure-6-observations-of-tidal-and-storm-surge-attenuation"><img alt="" class="figure-slide-image" src="https://figures.academia-assets.com/97942111/figure_006.jpg" /></a></figure><figure class="figure-slide-container"><a href="https://www.academia.edu/figures/25754288/figure-7-observations-of-tidal-and-storm-surge-attenuation"><img alt="" class="figure-slide-image" src="https://figures.academia-assets.com/97942111/figure_007.jpg" /></a></figure><figure class="figure-slide-container"><a href="https://www.academia.edu/figures/25754294/figure-8-observations-of-tidal-and-storm-surge-attenuation"><img alt="" class="figure-slide-image" src="https://figures.academia-assets.com/97942111/figure_008.jpg" /></a></figure><figure class="figure-slide-container"><a href="https://www.academia.edu/figures/25754298/table-1-values-denote-that-amplification-was-observed"><img alt="values denote that amplification was observed.

This is probably due to the complexity and length of the brewing procedure: longer, more complicated processing and presence of brewing sediment in the bottle allows more Si to dissolve out of the base products like hop, barley or even rice. As a side effect of fermentation, alcohol content was related to Si content.","owner":{"id":184662190,"first_name":"Patrick","middle_initials":null,"last_name":"Meire","page_name":"MeireP","domain_name":"independent","created_at":"2021-02-03T07:39:55.559-08:00","display_name":"Patrick Meire","url":"https://independent.academia.edu/MeireP"},"attachments":[],"research_interests":[{"id":498,"name":"Physics","url":"https://www.academia.edu/Documents/in/Physics"},{"id":511,"name":"Materials Science","url":"https://www.academia.edu/Documents/in/Materials_Science"},{"id":523,"name":"Chemistry","url":"https://www.academia.edu/Documents/in/Chemistry"},{"id":1907,"name":"Nutrition","url":"https://www.academia.edu/Documents/in/Nutrition"},{"id":7710,"name":"Biology","url":"https://www.academia.edu/Documents/in/Biology"},{"id":11406,"name":"Silicon","url":"https://www.academia.edu/Documents/in/Silicon"},{"id":67429,"name":"Brewing","url":"https://www.academia.edu/Documents/in/Brewing"},{"id":269129,"name":"Fermentation","url":"https://www.academia.edu/Documents/in/Fermentation"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") if (false) { Aedu.setUpFigureCarousel('profile-work-95887006-figures'); } }); </script> <div class="js-work-strip profile--work_container" data-work-id="95887005"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/95887005/Landscape_cultivation_alters_%CE%B4_30_Si_signature_in_terrestrial_ecosystems"><img alt="Research paper thumbnail of Landscape cultivation alters δ(30)Si signature in terrestrial ecosystems" class="work-thumbnail" src="https://attachments.academia-assets.com/97942107/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/95887005/Landscape_cultivation_alters_%CE%B4_30_Si_signature_in_terrestrial_ecosystems">Landscape cultivation alters δ(30)Si signature in terrestrial ecosystems</a></div><div class="wp-workCard_item"><span>Scientific reports</span><span>, Jan 13, 2015</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">Despite increasing recognition of the relevance of biological cycling for Si cycling in ecosystem...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">Despite increasing recognition of the relevance of biological cycling for Si cycling in ecosystems and for Si export from soils to fluvial systems, effects of human cultivation on the Si cycle are still relatively understudied.

The findings highlight the precarious health of guillemots in the southern North Sea, serving as vital bioindicators of marine pollution.","ai_title_tag":"Guillemot Pathology and Marine Pollution in 1993","publication_date":{"day":null,"month":null,"year":1998,"errors":{}},"publication_name":"Veterinary Record"},"translated_abstract":null,"internal_url":"https://www.academia.edu/95887003/Pathological_investigations_on_guillemots_Uria_aalge_stranded_on_the_Belgian_coast_during_the_winter_of_1993_94","translated_internal_url":"","created_at":"2023-01-29T00:36:08.603-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":184662190,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":97942110,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/97942110/thumbnails/1.jpg","file_name":"Guillemot.pdf","download_url":"https://www.academia.edu/attachments/97942110/download_file","bulk_download_file_name":"Pathological_investigations_on_guillemot.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/97942110/Guillemot-libre.pdf?1674982260=\u0026response-content-disposition=attachment%3B+filename%3DPathological_investigations_on_guillemot.pdf\u0026Expires=1743224695\u0026Signature=Ha0R01lO1pVgPL7XhmuH34d4cZSlQelFTkosGslfylDUdi6VgG7H3PHbjW0DNPkKT8kkN09tYPaZtW5vmqvHKc5T~wozZDnnweblsMI0l7pOk1k-MSZtm5JO0Zo5iCtJBmzI0LLOlFZujIo4pYRj-w5IERbPTdU-HchGWdBQxES-t8yQxB~4SsTC-3EWqsiwDqavNlJCupfw8vlq1OxTbI5aDoEwBoOL-8e8-2yAAlfi2Pal6sR8p1hYTxSeaMJFMYTKe9sqr5wbcjOjp5YFOIWifyYdcqkbBgE6~rjbZXW3kgZdY4Aq8C2QTkD9KXQKswpYhf-OevF~UIkwFcKJag__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Pathological_investigations_on_guillemots_Uria_aalge_stranded_on_the_Belgian_coast_during_the_winter_of_1993_94","translated_slug":"","page_count":5,"language":"en","content_type":"Work","summary":null,"owner":{"id":184662190,"first_name":"Patrick","middle_initials":null,"last_name":"Meire","page_name":"MeireP","domain_name":"independent","created_at":"2021-02-03T07:39:55.559-08:00","display_name":"Patrick Meire","url":"https://independent.academia.edu/MeireP"},"attachments":[{"id":97942110,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/97942110/thumbnails/1.jpg","file_name":"Guillemot.pdf","download_url":"https://www.academia.edu/attachments/97942110/download_file","bulk_download_file_name":"Pathological_investigations_on_guillemot.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/97942110/Guillemot-libre.pdf?1674982260=\u0026response-content-disposition=attachment%3B+filename%3DPathological_investigations_on_guillemot.pdf\u0026Expires=1743224695\u0026Signature=Ha0R01lO1pVgPL7XhmuH34d4cZSlQelFTkosGslfylDUdi6VgG7H3PHbjW0DNPkKT8kkN09tYPaZtW5vmqvHKc5T~wozZDnnweblsMI0l7pOk1k-MSZtm5JO0Zo5iCtJBmzI0LLOlFZujIo4pYRj-w5IERbPTdU-HchGWdBQxES-t8yQxB~4SsTC-3EWqsiwDqavNlJCupfw8vlq1OxTbI5aDoEwBoOL-8e8-2yAAlfi2Pal6sR8p1hYTxSeaMJFMYTKe9sqr5wbcjOjp5YFOIWifyYdcqkbBgE6~rjbZXW3kgZdY4Aq8C2QTkD9KXQKswpYhf-OevF~UIkwFcKJag__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":7710,"name":"Biology","url":"https://www.academia.edu/Documents/in/Biology"},{"id":24377,"name":"Mortality","url":"https://www.academia.edu/Documents/in/Mortality"},{"id":26327,"name":"Medicine","url":"https://www.academia.edu/Documents/in/Medicine"},{"id":35414,"name":"Veterinary","url":"https://www.academia.edu/Documents/in/Veterinary"},{"id":40862,"name":"Belgium","url":"https://www.academia.edu/Documents/in/Belgium"},{"id":93298,"name":"Fossil Fuels","url":"https://www.academia.edu/Documents/in/Fossil_Fuels"},{"id":96324,"name":"Birds","url":"https://www.academia.edu/Documents/in/Birds"},{"id":564878,"name":"Body Weight","url":"https://www.academia.edu/Documents/in/Body_Weight"},{"id":644860,"name":"Veterinary Sciences","url":"https://www.academia.edu/Documents/in/Veterinary_Sciences"},{"id":980394,"name":"Acute Toxicity","url":"https://www.academia.edu/Documents/in/Acute_Toxicity"},{"id":1004785,"name":"Hemorrhage","url":"https://www.academia.edu/Documents/in/Hemorrhage"},{"id":1312021,"name":"Environmental Exposure","url":"https://www.academia.edu/Documents/in/Environmental_Exposure"},{"id":1729106,"name":"Pathological","url":"https://www.academia.edu/Documents/in/Pathological"}],"urls":[{"id":28485832,"url":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1136%2Fvr.143.14.387"}]}, dispatcherData: dispatcherData });

Ecological response surfaces are derived for 10 estuarine macrobenthic species. Logistic regression is applied on a large data set, predicting the probability of occurrence of macrobenthic species in the Schelde estuary as a response to the predictor variables salinity, depth, current velocity and sediment characteristics. Single logistic regression provides good descriptions of the occurrence along 1 environmental variable. The response surfaces obtained by multiple logistic regression provide estimates of the probability of species occurrence across the spatial extent of the Schelde estuary with a relatively high degree of success. Results from subsampling 50% of the original data 10 times indicate that final models were stable. A visual geographical comparison is presented between the mapped probability surfaces and the species occurrence maps. We conclude that where patterns of distribution are strongly and directly coupled to physicochemical processes, as is the case at the estuarine macro-and meso-scale, our modelling approach was capable of predicting macrobenthic species distributions with a relatively high degree of success, although processes controlling estuarine macrobenthic distribution cannot be determined using this method.

Au large de la côte est de Belgique, la dominance des nématodes bactérivores, la quasi-absence des prédateurs, la très faible diversité spécifique des communautés de ce groupe et la pauvreté des métazoaires supérieurs peuvent trouver leur expl ication d'une part dans l'augmentation de l'apport en nutriments et d'autre part dans la grande quantité de po llution diffuse.","owner":{"id":184662190,"first_name":"Patrick","middle_initials":null,"last_name":"Meire","page_name":"MeireP","domain_name":"independent","created_at":"2021-02-03T07:39:55.559-08:00","display_name":"Patrick Meire","url":"https://independent.academia.edu/MeireP"},"attachments":[{"id":97942103,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/97942103/thumbnails/1.jpg","file_name":"286799.pdf","download_url":"https://www.academia.edu/attachments/97942103/download_file","bulk_download_file_name":"Diversity_of_the_nematode_communities_in.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/97942103/286799-libre.pdf?1674982304=\u0026response-content-disposition=attachment%3B+filename%3DDiversity_of_the_nematode_communities_in.pdf\u0026Expires=1743224695\u0026Signature=Jgb~CvNX2f~lurU4KFw-OlbU2CgZRO28CvMazP2huahtDlnWCSqy~3zcu5H6I8eGtM-Dlr6JNjz4Rg-PvDVRupzpsiyrXgID-SW3BCy~MGlwZlMnTZseLwTedJyyBowZIb2llpA3XTUB0ZYt9WtHX0eJui2qMP1bDYkbaTvtqRX1rKQWeIVP5fUJO8T~kOnIM0HY1Na2xOxscjr~--K8tsbt9cxP~soyOxC2Zqa1P86puGCBngjZqJoo9Pd7-LH-FQS~VAnKmeGZ4fTs2r47db8gEVYvYc37xu~oWYRjlUjJghG-wQ~xqGql8njkyHufpIaKkD6RrLLFTbWPKn5klg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":415,"name":"Oceanography","url":"https://www.academia.edu/Documents/in/Oceanography"},{"id":7710,"name":"Biology","url":"https://www.academia.edu/Documents/in/Biology"},{"id":9846,"name":"Ecology","url":"https://www.academia.edu/Documents/in/Ecology"},{"id":154925,"name":"Trophic Level","url":"https://www.academia.edu/Documents/in/Trophic_Level"},{"id":168668,"name":"Species Diversity","url":"https://www.academia.edu/Documents/in/Species_Diversity"},{"id":531422,"name":"North Sea","url":"https://www.academia.edu/Documents/in/North_Sea"},{"id":876158,"name":"Diversity index","url":"https://www.academia.edu/Documents/in/Diversity_index"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") if (false) { Aedu.setUpFigureCarousel('profile-work-95887000-figures'); } }); </script> <div class="js-work-strip profile--work_container" data-work-id="95886999"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/95886999/The_effects_of_sewer_infrastructure_on_water_quality_implications_for_land_use_studies"><img alt="Research paper thumbnail of The effects of sewer infrastructure on water quality: implications for land use studies" class="work-thumbnail" src="https://attachments.academia-assets.com/97942101/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/95886999/The_effects_of_sewer_infrastructure_on_water_quality_implications_for_land_use_studies">The effects of sewer infrastructure on water quality: implications for land use studies</a></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">The European Water Framework Directive requires a good ecological status of the European water bo...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">The European Water Framework Directive requires a good ecological status of the European water bodies and the necessary measures to obtain this have to be implemented.

To establish its role in the benthic foodweb, and to assess the impact of human activities, data on density, age composition, biomass and growth were collected from several tidal flats in the Oosterschelde between 1980 and 1990. To estimate the overall biomass development of the cockle, a simple model was used, in which three growing seasons are defined for the cockle population. A standard individual growth curve was constructed. A negative exponential mortality function was assumed to estimate the number of recruits. By combining the estimated number of recruits, the estimated specific mortality rate and the standard individual growth curve, numbers and biomass of each age group in the Oosterschelde population were estimated. Average biomass (including shell organics) per m 2 of tidal flat in August varied from 140 g AFDW in 1980 to 21 g AFDW in 1989, implying a total cockle stock on all tidal flats of 19170 to 2350 tonnes AFDW (72 x 10 3 to 9 X 10 3 tonnes flesh), respectively. A comparison of results from field surveys and the reconstructed stock estimations showed large deviations. However, an uncertainty analysis performed on the model showed that most field data fitted within the minimum and maximum biomass calculated. Total biomass is largely dependent on the strength of certain year classes. In this respect, the year classes 1979, 1982, and 1985 were good. Effects of the construction of the storm-surge barrier and the compartmentalisation dams could not be demonstrated. The year-to-year variation in cockle stocks, assessed in the way described in this paper should be regarded as relative, because a systematic survey of the intertidal flats was not performed every year, but population dynamics from selected stations were used instead.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="9a770ccdab6f79ff307a29c449d78b84" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":97942100,"asset_id":95886997,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/97942100/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="95886997"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="95886997"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 95886997; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=95886997]").text(description); $(".js-view-count[data-work-id=95886997]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 95886997; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='95886997']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "9a770ccdab6f79ff307a29c449d78b84" } } $('.js-work-strip[data-work-id=95886997]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":95886997,"title":"Variability in stock assessment of cockles (Cerastoderma edule L.) in the Oosterschelde (in 1980–1990), in relation to environmental factors","translated_title":"","metadata":{"publisher":"Springer Nature","grobid_abstract":"The edible cockle (Cerastoderma edule L.) is a dominant suspension feeder in the Oosterschelde, a 351 km 2 tidal bay in the SW Netherlands.

Data on macrobenthos were collected from 1979 to 1989 on five different tidal flats. Changes in sediment texture and hydrodynamic factors during the construction and after the completion of the coastal engineering project were taken into account. Three severe winters in a row caused more disturbance in the population of the main predator of S. armiger than did the hydrodynamical changes. A temporary prolongation of the emersion time (in 1986 and 1987) caused a temporary decrease in juvenile A. marina. But afterwards they still occupy the samè nursery grounds'.

They are very productive biomes and support many important ecosystem functions: biogeochemical cycling and movement of nutrients, mitigation of floods, maintenance of biodiversity and biological production. Human pressure on estuaries is very high. On the other hand, it is recognized that estuaries have a unique functional and structural biodiversity. Therefore, these ecosystems are particularly important for integrating sound ecological management with sustainable economics. These opportunities are explored for the Scheldt estuary, a well-documented system with an exceptional tidal freshwater area. In this article a description of the Scheldt estuary is presented, illustrating that human influence is intertwined with natural dynamics. Hydrology, geomorphology, trophic status and diversity are discussed, and possible future trends in both natural evolution and management are argued.</span></div><div class="wp-workCard_item"><div class="carousel-container carousel-container--sm" id="profile-work-99924468-figures"><div class="prev-slide-container js-prev-button-container"><button aria-label="Previous" class="carousel-navigation-button js-profile-work-99924468-figures-prev"><span class="material-symbols-outlined" style="font-size: 24px" translate="no">arrow_back_ios</span></button></div><div class="slides-container js-slides-container"><figure class="figure-slide-container"><a href="https://www.academia.edu/figures/53325021/figure-1-map-of-the-scheldt-estuary"><img alt="Figure 1.

Intertidal habitat was also lost due to dike building. In order to protect the land against storm floods from the North Sea all dikes along the estuary (more than 700 km) have been heightened and strengthened. Therefore, the base of the dikes needed to be widened, which was mostly done on the marshes and not on the landside of the dike. By now, over more than 50% of the total length of the estuary lacks tidal marshes in front of the dike. This disrupted the connectivity of marshes along the salinity gradient.

In the Scheldt estuary, the turbidity maximum is situated at about 110 km from the mouth during dry periods and at about 50 km during wet periods (Wollast, 1988).

Nevertheless, insitu observations of storm surge attenuation within wetlands are still scarce. We present water level measurements along a 4 km intertidal channel and on the surrounding marsh platform for regular spring to neap tides and two major storm surge tides, showing the effects of flood wave height and marsh geomorphology on the amount of flood wave attenuation. Undermarsh tides with peak water levels below marsh platform elevation are mostly amplified (up to 4 cm/km) within the channels. Overmarsh tides with peak water levels above the marsh platform are generally attenuated along the channels, with maximum attenuation rates of 5 cm/km for tides that inundate the marsh platform by 0.5-1.0 m. For lower or higher flood waves, including storm surges, attenuation rates decrease. Furthermore, the observations show that the maximum attenuation occurs along narrow channel transects where the width of the platform is larger, whereas attenuation rates are lower along wider channels with smaller adjacent marsh platforms. These observations are confirmed by an analytical approximation of tidal wave propagation through convergent channels. The analytical model indicates that differences in attenuation rates are induced by variations in the cross-channel averaged friction between channel sections and between tides with varying peak water levels. Finally, the highest attenuation rates of up to 70 cm/km are observed over short distances on the vegetated marsh platform. We conclude that this 2 study provides an empirical basis for the wider implementation of nature-based flood defense 18 strategies.</span></div><div class="wp-workCard_item"><div class="carousel-container carousel-container--sm" id="profile-work-95887013-figures"><div class="prev-slide-container js-prev-button-container"><button aria-label="Previous" class="carousel-navigation-button js-profile-work-95887013-figures-prev"><span class="material-symbols-outlined" style="font-size: 24px" translate="no">arrow_back_ios</span></button></div><div class="slides-container js-slides-container"><figure class="figure-slide-container"><a href="https://www.academia.edu/figures/25754256/figure-1-observations-of-tidal-and-storm-surge-attenuation"><img alt="" class="figure-slide-image" src="https://figures.academia-assets.com/97942111/figure_001.jpg" /></a></figure><figure class="figure-slide-container"><a href="https://www.academia.edu/figures/25754263/figure-2-observations-of-tidal-and-storm-surge-attenuation"><img alt="" class="figure-slide-image" src="https://figures.academia-assets.com/97942111/figure_002.jpg" /></a></figure><figure class="figure-slide-container"><a href="https://www.academia.edu/figures/25754269/figure-3-observations-of-tidal-and-storm-surge-attenuation"><img alt="" class="figure-slide-image" src="https://figures.academia-assets.com/97942111/figure_003.jpg" /></a></figure><figure class="figure-slide-container"><a href="https://www.academia.edu/figures/25754273/figure-4-observations-of-tidal-and-storm-surge-attenuation"><img alt="" class="figure-slide-image" src="https://figures.academia-assets.com/97942111/figure_004.jpg" /></a></figure><figure class="figure-slide-container"><a href="https://www.academia.edu/figures/25754277/figure-5-observations-of-tidal-and-storm-surge-attenuation"><img alt="" class="figure-slide-image" src="https://figures.academia-assets.com/97942111/figure_005.jpg" /></a></figure><figure class="figure-slide-container"><a href="https://www.academia.edu/figures/25754284/figure-6-observations-of-tidal-and-storm-surge-attenuation"><img alt="" class="figure-slide-image" src="https://figures.academia-assets.com/97942111/figure_006.jpg" /></a></figure><figure class="figure-slide-container"><a href="https://www.academia.edu/figures/25754288/figure-7-observations-of-tidal-and-storm-surge-attenuation"><img alt="" class="figure-slide-image" src="https://figures.academia-assets.com/97942111/figure_007.jpg" /></a></figure><figure class="figure-slide-container"><a href="https://www.academia.edu/figures/25754294/figure-8-observations-of-tidal-and-storm-surge-attenuation"><img alt="" class="figure-slide-image" src="https://figures.academia-assets.com/97942111/figure_008.jpg" /></a></figure><figure class="figure-slide-container"><a href="https://www.academia.edu/figures/25754298/table-1-values-denote-that-amplification-was-observed"><img alt="values denote that amplification was observed.

We conclude that this 2 study provides an empirical basis for the wider implementation of nature-based flood defense 18 strategies.","owner":{"id":184662190,"first_name":"Patrick","middle_initials":null,"last_name":"Meire","page_name":"MeireP","domain_name":"independent","created_at":"2021-02-03T07:39:55.559-08:00","display_name":"Patrick Meire","url":"https://independent.academia.edu/MeireP"},"attachments":[{"id":97942111,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/97942111/thumbnails/1.jpg","file_name":"10505.pdf","download_url":"https://www.academia.edu/attachments/97942111/download_file","bulk_download_file_name":"Observations_of_tidal_and_storm_surge_at.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/97942111/10505-libre.pdf?1674982274=\u0026response-content-disposition=attachment%3B+filename%3DObservations_of_tidal_and_storm_surge_at.pdf\u0026Expires=1743224694\u0026Signature=MHsC3evubGCkKckaE8Pzwry2bV3pV8p3c8h-cHqgyTUE0y7XWN6YZVtcNq9SzPT6galJmFojfHSjFHVPRQlZI5snb21ceONogfjXUrzD2EyLWybWDVJXmXjsn7fvG6VtW4P9bgMWdrwvLJbajqY8ztpr1o~xe92IjmwgXmBVCGvf57-A~hr6PdCdxN216kbI8dEwc71xAju4o2piSYPg30F2DW5qTlHlIzr5pEJapQXZjyES-DjBVAi-ZGi~XCrKGa5ZHRntHQRiexeqH-WUx90IBiiZGYdmvV4E22ljwZvfk2iBBfjD~bgfThIH5IDYNNvBh~W4kXc8RH3xjEUB8Q__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":400,"name":"Earth Sciences","url":"https://www.academia.edu/Documents/in/Earth_Sciences"},{"id":402,"name":"Environmental Science","url":"https://www.academia.edu/Documents/in/Environmental_Science"},{"id":406,"name":"Geology","url":"https://www.academia.edu/Documents/in/Geology"},{"id":415,"name":"Oceanography","url":"https://www.academia.edu/Documents/in/Oceanography"},{"id":7710,"name":"Biology","url":"https://www.academia.edu/Documents/in/Biology"},{"id":47884,"name":"Biological Sciences","url":"https://www.academia.edu/Documents/in/Biological_Sciences"},{"id":58054,"name":"Environmental Sciences","url":"https://www.academia.edu/Documents/in/Environmental_Sciences"},{"id":162136,"name":"Storm","url":"https://www.academia.edu/Documents/in/Storm"},{"id":216197,"name":"Biological Oceanography and Limnology","url":"https://www.academia.edu/Documents/in/Biological_Oceanography_and_Limnology"},{"id":398869,"name":"Intertidal Zone","url":"https://www.academia.edu/Documents/in/Intertidal_Zone"},{"id":556983,"name":"Storm surge","url":"https://www.academia.edu/Documents/in/Storm_surge"},{"id":580672,"name":"Tidal Flat","url":"https://www.academia.edu/Documents/in/Tidal_Flat"},{"id":951108,"name":"Attenuation","url":"https://www.academia.edu/Documents/in/Attenuation"},{"id":956838,"name":"Marsh","url":"https://www.academia.edu/Documents/in/Marsh"},{"id":1227220,"name":"Surge","url":"https://www.academia.edu/Documents/in/Surge"},{"id":3647976,"name":"Flood Myth","url":"https://www.academia.edu/Documents/in/Flood_Myth"}],"urls":[{"id":28485835,"url":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1002%2Flno.10104"}]}, dispatcherData: dispatcherData });

Three decades of research have yielded evidence of a role for Si in human physiology: it plays an essential role in bone mineral density and reduces the biological availability of aluminium. We analysed 119 Belgian beers: highest dissolved Si concentrations were found in high fermentation, traditionally brewed ales. Concentrations ranged between 214 and 2,071 μmol L − 1. This is probably due to the complexity and length of the brewing procedure: longer, more complicated processing and presence of brewing sediment in the bottle allows more Si to dissolve out of the base products like hop, barley or even rice. As a side effect of fermentation, alcohol content was related to Si content.","owner":{"id":184662190,"first_name":"Patrick","middle_initials":null,"last_name":"Meire","page_name":"MeireP","domain_name":"independent","created_at":"2021-02-03T07:39:55.559-08:00","display_name":"Patrick Meire","url":"https://independent.academia.edu/MeireP"},"attachments":[],"research_interests":[{"id":498,"name":"Physics","url":"https://www.academia.edu/Documents/in/Physics"},{"id":511,"name":"Materials Science","url":"https://www.academia.edu/Documents/in/Materials_Science"},{"id":523,"name":"Chemistry","url":"https://www.academia.edu/Documents/in/Chemistry"},{"id":1907,"name":"Nutrition","url":"https://www.academia.edu/Documents/in/Nutrition"},{"id":7710,"name":"Biology","url":"https://www.academia.edu/Documents/in/Biology"},{"id":11406,"name":"Silicon","url":"https://www.academia.edu/Documents/in/Silicon"},{"id":67429,"name":"Brewing","url":"https://www.academia.edu/Documents/in/Brewing"},{"id":269129,"name":"Fermentation","url":"https://www.academia.edu/Documents/in/Fermentation"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") if (false) { Aedu.setUpFigureCarousel('profile-work-95887006-figures'); } }); </script> <div class="js-work-strip profile--work_container" data-work-id="95887005"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/95887005/Landscape_cultivation_alters_%CE%B4_30_Si_signature_in_terrestrial_ecosystems"><img alt="Research paper thumbnail of Landscape cultivation alters δ(30)Si signature in terrestrial ecosystems" class="work-thumbnail" src="https://attachments.academia-assets.com/97942107/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/95887005/Landscape_cultivation_alters_%CE%B4_30_Si_signature_in_terrestrial_ecosystems">Landscape cultivation alters δ(30)Si signature in terrestrial ecosystems</a></div><div class="wp-workCard_item"><span>Scientific reports</span><span>, Jan 13, 2015</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">Despite increasing recognition of the relevance of biological cycling for Si cycling in ecosystem...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">Despite increasing recognition of the relevance of biological cycling for Si cycling in ecosystems and for Si export from soils to fluvial systems, effects of human cultivation on the Si cycle are still relatively understudied.

The findings highlight the precarious health of guillemots in the southern North Sea, serving as vital bioindicators of marine pollution.","ai_title_tag":"Guillemot Pathology and Marine Pollution in 1993","publication_date":{"day":null,"month":null,"year":1998,"errors":{}},"publication_name":"Veterinary Record"},"translated_abstract":null,"internal_url":"https://www.academia.edu/95887003/Pathological_investigations_on_guillemots_Uria_aalge_stranded_on_the_Belgian_coast_during_the_winter_of_1993_94","translated_internal_url":"","created_at":"2023-01-29T00:36:08.603-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":184662190,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":97942110,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/97942110/thumbnails/1.jpg","file_name":"Guillemot.pdf","download_url":"https://www.academia.edu/attachments/97942110/download_file","bulk_download_file_name":"Pathological_investigations_on_guillemot.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/97942110/Guillemot-libre.pdf?1674982260=\u0026response-content-disposition=attachment%3B+filename%3DPathological_investigations_on_guillemot.pdf\u0026Expires=1743224695\u0026Signature=Ha0R01lO1pVgPL7XhmuH34d4cZSlQelFTkosGslfylDUdi6VgG7H3PHbjW0DNPkKT8kkN09tYPaZtW5vmqvHKc5T~wozZDnnweblsMI0l7pOk1k-MSZtm5JO0Zo5iCtJBmzI0LLOlFZujIo4pYRj-w5IERbPTdU-HchGWdBQxES-t8yQxB~4SsTC-3EWqsiwDqavNlJCupfw8vlq1OxTbI5aDoEwBoOL-8e8-2yAAlfi2Pal6sR8p1hYTxSeaMJFMYTKe9sqr5wbcjOjp5YFOIWifyYdcqkbBgE6~rjbZXW3kgZdY4Aq8C2QTkD9KXQKswpYhf-OevF~UIkwFcKJag__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Pathological_investigations_on_guillemots_Uria_aalge_stranded_on_the_Belgian_coast_during_the_winter_of_1993_94","translated_slug":"","page_count":5,"language":"en","content_type":"Work","summary":null,"owner":{"id":184662190,"first_name":"Patrick","middle_initials":null,"last_name":"Meire","page_name":"MeireP","domain_name":"independent","created_at":"2021-02-03T07:39:55.559-08:00","display_name":"Patrick Meire","url":"https://independent.academia.edu/MeireP"},"attachments":[{"id":97942110,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/97942110/thumbnails/1.jpg","file_name":"Guillemot.pdf","download_url":"https://www.academia.edu/attachments/97942110/download_file","bulk_download_file_name":"Pathological_investigations_on_guillemot.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/97942110/Guillemot-libre.pdf?1674982260=\u0026response-content-disposition=attachment%3B+filename%3DPathological_investigations_on_guillemot.pdf\u0026Expires=1743224695\u0026Signature=Ha0R01lO1pVgPL7XhmuH34d4cZSlQelFTkosGslfylDUdi6VgG7H3PHbjW0DNPkKT8kkN09tYPaZtW5vmqvHKc5T~wozZDnnweblsMI0l7pOk1k-MSZtm5JO0Zo5iCtJBmzI0LLOlFZujIo4pYRj-w5IERbPTdU-HchGWdBQxES-t8yQxB~4SsTC-3EWqsiwDqavNlJCupfw8vlq1OxTbI5aDoEwBoOL-8e8-2yAAlfi2Pal6sR8p1hYTxSeaMJFMYTKe9sqr5wbcjOjp5YFOIWifyYdcqkbBgE6~rjbZXW3kgZdY4Aq8C2QTkD9KXQKswpYhf-OevF~UIkwFcKJag__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":7710,"name":"Biology","url":"https://www.academia.edu/Documents/in/Biology"},{"id":24377,"name":"Mortality","url":"https://www.academia.edu/Documents/in/Mortality"},{"id":26327,"name":"Medicine","url":"https://www.academia.edu/Documents/in/Medicine"},{"id":35414,"name":"Veterinary","url":"https://www.academia.edu/Documents/in/Veterinary"},{"id":40862,"name":"Belgium","url":"https://www.academia.edu/Documents/in/Belgium"},{"id":93298,"name":"Fossil Fuels","url":"https://www.academia.edu/Documents/in/Fossil_Fuels"},{"id":96324,"name":"Birds","url":"https://www.academia.edu/Documents/in/Birds"},{"id":564878,"name":"Body Weight","url":"https://www.academia.edu/Documents/in/Body_Weight"},{"id":644860,"name":"Veterinary Sciences","url":"https://www.academia.edu/Documents/in/Veterinary_Sciences"},{"id":980394,"name":"Acute Toxicity","url":"https://www.academia.edu/Documents/in/Acute_Toxicity"},{"id":1004785,"name":"Hemorrhage","url":"https://www.academia.edu/Documents/in/Hemorrhage"},{"id":1312021,"name":"Environmental Exposure","url":"https://www.academia.edu/Documents/in/Environmental_Exposure"},{"id":1729106,"name":"Pathological","url":"https://www.academia.edu/Documents/in/Pathological"}],"urls":[{"id":28485832,"url":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1136%2Fvr.143.14.387"}]}, dispatcherData: dispatcherData });

Ecological response surfaces are derived for 10 estuarine macrobenthic species. Logistic regression is applied on a large data set, predicting the probability of occurrence of macrobenthic species in the Schelde estuary as a response to the predictor variables salinity, depth, current velocity and sediment characteristics. Single logistic regression provides good descriptions of the occurrence along 1 environmental variable. The response surfaces obtained by multiple logistic regression provide estimates of the probability of species occurrence across the spatial extent of the Schelde estuary with a relatively high degree of success. Results from subsampling 50% of the original data 10 times indicate that final models were stable. A visual geographical comparison is presented between the mapped probability surfaces and the species occurrence maps. We conclude that where patterns of distribution are strongly and directly coupled to physicochemical processes, as is the case at the estuarine macro-and meso-scale, our modelling approach was capable of predicting macrobenthic species distributions with a relatively high degree of success, although processes controlling estuarine macrobenthic distribution cannot be determined using this method.

Au large de la côte est de Belgique, la dominance des nématodes bactérivores, la quasi-absence des prédateurs, la très faible diversité spécifique des communautés de ce groupe et la pauvreté des métazoaires supérieurs peuvent trouver leur expl ication d'une part dans l'augmentation de l'apport en nutriments et d'autre part dans la grande quantité de po llution diffuse.","owner":{"id":184662190,"first_name":"Patrick","middle_initials":null,"last_name":"Meire","page_name":"MeireP","domain_name":"independent","created_at":"2021-02-03T07:39:55.559-08:00","display_name":"Patrick Meire","url":"https://independent.academia.edu/MeireP"},"attachments":[{"id":97942103,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/97942103/thumbnails/1.jpg","file_name":"286799.pdf","download_url":"https://www.academia.edu/attachments/97942103/download_file","bulk_download_file_name":"Diversity_of_the_nematode_communities_in.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/97942103/286799-libre.pdf?1674982304=\u0026response-content-disposition=attachment%3B+filename%3DDiversity_of_the_nematode_communities_in.pdf\u0026Expires=1743224695\u0026Signature=Jgb~CvNX2f~lurU4KFw-OlbU2CgZRO28CvMazP2huahtDlnWCSqy~3zcu5H6I8eGtM-Dlr6JNjz4Rg-PvDVRupzpsiyrXgID-SW3BCy~MGlwZlMnTZseLwTedJyyBowZIb2llpA3XTUB0ZYt9WtHX0eJui2qMP1bDYkbaTvtqRX1rKQWeIVP5fUJO8T~kOnIM0HY1Na2xOxscjr~--K8tsbt9cxP~soyOxC2Zqa1P86puGCBngjZqJoo9Pd7-LH-FQS~VAnKmeGZ4fTs2r47db8gEVYvYc37xu~oWYRjlUjJghG-wQ~xqGql8njkyHufpIaKkD6RrLLFTbWPKn5klg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":415,"name":"Oceanography","url":"https://www.academia.edu/Documents/in/Oceanography"},{"id":7710,"name":"Biology","url":"https://www.academia.edu/Documents/in/Biology"},{"id":9846,"name":"Ecology","url":"https://www.academia.edu/Documents/in/Ecology"},{"id":154925,"name":"Trophic Level","url":"https://www.academia.edu/Documents/in/Trophic_Level"},{"id":168668,"name":"Species Diversity","url":"https://www.academia.edu/Documents/in/Species_Diversity"},{"id":531422,"name":"North Sea","url":"https://www.academia.edu/Documents/in/North_Sea"},{"id":876158,"name":"Diversity index","url":"https://www.academia.edu/Documents/in/Diversity_index"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") if (false) { Aedu.setUpFigureCarousel('profile-work-95887000-figures'); } }); </script> <div class="js-work-strip profile--work_container" data-work-id="95886999"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/95886999/The_effects_of_sewer_infrastructure_on_water_quality_implications_for_land_use_studies"><img alt="Research paper thumbnail of The effects of sewer infrastructure on water quality: implications for land use studies" class="work-thumbnail" src="https://attachments.academia-assets.com/97942101/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/95886999/The_effects_of_sewer_infrastructure_on_water_quality_implications_for_land_use_studies">The effects of sewer infrastructure on water quality: implications for land use studies</a></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">The European Water Framework Directive requires a good ecological status of the European water bo...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">The European Water Framework Directive requires a good ecological status of the European water bodies and the necessary measures to obtain this have to be implemented.

To establish its role in the benthic foodweb, and to assess the impact of human activities, data on density, age composition, biomass and growth were collected from several tidal flats in the Oosterschelde between 1980 and 1990. To estimate the overall biomass development of the cockle, a simple model was used, in which three growing seasons are defined for the cockle population. A standard individual growth curve was constructed. A negative exponential mortality function was assumed to estimate the number of recruits. By combining the estimated number of recruits, the estimated specific mortality rate and the standard individual growth curve, numbers and biomass of each age group in the Oosterschelde population were estimated. Average biomass (including shell organics) per m 2 of tidal flat in August varied from 140 g AFDW in 1980 to 21 g AFDW in 1989, implying a total cockle stock on all tidal flats of 19170 to 2350 tonnes AFDW (72 x 10 3 to 9 X 10 3 tonnes flesh), respectively. A comparison of results from field surveys and the reconstructed stock estimations showed large deviations. However, an uncertainty analysis performed on the model showed that most field data fitted within the minimum and maximum biomass calculated. Total biomass is largely dependent on the strength of certain year classes. In this respect, the year classes 1979, 1982, and 1985 were good. Effects of the construction of the storm-surge barrier and the compartmentalisation dams could not be demonstrated. The year-to-year variation in cockle stocks, assessed in the way described in this paper should be regarded as relative, because a systematic survey of the intertidal flats was not performed every year, but population dynamics from selected stations were used instead.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="9a770ccdab6f79ff307a29c449d78b84" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":97942100,"asset_id":95886997,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/97942100/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="95886997"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="95886997"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 95886997; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=95886997]").text(description); $(".js-view-count[data-work-id=95886997]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 95886997; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='95886997']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "9a770ccdab6f79ff307a29c449d78b84" } } $('.js-work-strip[data-work-id=95886997]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":95886997,"title":"Variability in stock assessment of cockles (Cerastoderma edule L.) in the Oosterschelde (in 1980–1990), in relation to environmental factors","translated_title":"","metadata":{"publisher":"Springer Nature","grobid_abstract":"The edible cockle (Cerastoderma edule L.) is a dominant suspension feeder in the Oosterschelde, a 351 km 2 tidal bay in the SW Netherlands.

Data on macrobenthos were collected from 1979 to 1989 on five different tidal flats. Changes in sediment texture and hydrodynamic factors during the construction and after the completion of the coastal engineering project were taken into account. Three severe winters in a row caused more disturbance in the population of the main predator of S. armiger than did the hydrodynamical changes. A temporary prolongation of the emersion time (in 1986 and 1987) caused a temporary decrease in juvenile A. marina. But afterwards they still occupy the samè nursery grounds'.

Furthermore, Si research in estuaries has mainly been focused on subtidal benthic sediments and uptake and recycling by diatom communities. The biogeochemical cycling of Si in tidal wetlands, which can contain large amounts of Si, has thus far been neglected. We have conducted several whole ecosystem Si mass-balances on a freshwater marsh located in the Schelde estuary (6 tidal cycles, 2 with BSi included). Our measurements show that the freshwater marsh acts as an important source of dissolved Si to the main river (1-18% more export than import, on average 0.114 g m)2). This export is compensated by import of amorphous silica into the marsh (19-55% more import than export). The marsh was shown to act as silica recycler, resupplying biologically available dissolved Si to the estuarine ecosystem. Extrapolations show that during summer and spring months, when dissolved silica is depleted due to diatom growth, almost half of the total dissolved silica load in the main river channel could result from marsh recycling.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="b2f26e8e586f96dfa51c2231c953fae1" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":97942112,"asset_id":95886994,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/97942112/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="95886994"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="95886994"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 95886994; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=95886994]").text(description); $(".js-view-count[data-work-id=95886994]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 95886994; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='95886994']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "b2f26e8e586f96dfa51c2231c953fae1" } } $('.js-work-strip[data-work-id=95886994]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":95886994,"title":"Freshwater marshes as dissolved silica recyclers in an estuarine environment (Schelde estuary, Belgium)","translated_title":"","metadata":{"publisher":"Springer Science and Business Media LLC","ai_title_tag":"Marshes as Dissolved Silica Recyclers in Estuaries","grobid_abstract":"Compared to knowledge about N and P processing in the aquatic continuum of lakes, wetlands and estuaries, knowledge concerning transport and cycling of Si is only fragmentary.
