A number of socio-economic factors such as poverty, the population explosion and the lack of hydrological and ancillary data, are at the root of these problems. Droughts and climatic variability aggravate the vulnerability of the continent and make sustainable water resources development a real challenge. Inadequate levels and coverage of water services plague both urban and rural communities, with attendant health risks. The major problems are examined, including diminishing per capita freshwater resources, poor management and inefficient utilization, and lasting solutions are proffered. The conclusion is that the hydrological, engineering and social sciences have important roles to play in enabling African economies to overcome the acute and often devastating water problems confronting them now and in future decades.

Aerial photographs were used to assess the land use and land cover developments of the system 6c watershed as it were in 1965, 1975, and 1987 while IKONOS 2 imagery was used to determine the level of developments on the watershed as at 2005. Overlay analysis was used to carry out change detection which was presented in matrix format. The built up area is the dominant land cover for 1975, 1987 and 2005. The greatest expansion of the builtup area occurred between 1965 and 1975, during which it grew at the rate of 87.87 hectare per annum. Also, the greatest loss especially of the wetland with annual loss of 57.71 hectare per annum was recorded during the same period.

The major sources of surface water in the Sudano-Sahelian zone are the Lake Chad, K. Yobe- Hadejia, Sokoto-Rima and Gongola river systems. The seasonal and long-term variations in the flow of the rivers underline the importance of over-year storage as a means of making optimum use of the water resources. For example, most of the Sahelian rivers dried up during the 1973 and 1984 droughts, making the existing manmade reservoirs look like oases in the desert. The high rates of evaporation from the reser颅 voirs, persistent droughts, faulty designs and operation of the multi颅 purpose dams and reservoirs have often led to drastic reduction in the areas of wetlands and available water in downstream areas.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="3e2ea139fe3998fb0e30f8020c443e6e" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":77436672,"asset_id":66119277,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/77436672/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="66119277"><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="66119277"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 66119277;

Weekly water level measurements for 12 wells were carried out for dry season periods between November 1995-April 1996 and November 2007-April 2008. The drawdown arising from climate variability/change and urbanization impacts between 1995 and 2008 was estimated using overlay analysis and mapped as digital terrain model (DTM). Average annual drawdown rate of 0.07 m per annum was estimated with a general drawdown of 0.8 m in the groundwater table of the dry season. This resulted in low production of water in most wells during the dry season periods. Annual maintenance of the wells during the dry season becomes imperative and this infringes on the economic wellbeing of the people. A complimentary extension of the surface water distribution network to the area is recommended.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><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="66119276"><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="66119276"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 66119276; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=66119276]").text(description); $(".js-view-count[data-work-id=66119276]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 66119276; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='66119276']"); 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 (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=66119276]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":66119276,"title":"Variability of water table in high density low income groundwater utilization area in Lagos, Nigeria","internal_url":"https://www.academia.edu/66119276/Variability_of_water_table_in_high_density_low_income_groundwater_utilization_area_in_Lagos_Nigeria","owner_id":51962856,"coauthors_can_edit":true,"owner":{"id":51962856,"first_name":"Lekan","middle_initials":"","last_name":"Oyebande","page_name":"LekanOyebande","domain_name":"unilag","created_at":"2016-08-11T12:20:39.723-07:00","display_name":"Lekan Oyebande","url":"https://unilag.academia.edu/LekanOyebande"},"attachments":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="66119275"><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/66119275/Flow_simulation_in_an_ungauged_basin_using_digital_elevation_model"><img alt="Research paper thumbnail of Flow simulation in an ungauged basin using digital elevation model" class="work-thumbnail" src="https://attachments.academia-assets.com/77436712/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/66119275/Flow_simulation_in_an_ungauged_basin_using_digital_elevation_model">Flow simulation in an ungauged basin using digital elevation model</a></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">The rate of water withdrawal from both surface and groundwater has also increased dramatically in...</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 rate of water withdrawal from both surface and groundwater has also increased dramatically in the last two decades.

Climate variability and change caused reduced inflows into dam reservoirs resulting in the drastic and steady drop in the hydroelectric power generated by dams the Kainji and other dams in Nigeria between 1973 and 1994 and in 2003. The phenomenon has exacerbated competition for water between energy and other sectors of the economy such as agriculture.

The topographic map of 1965 and Landsat ETM images of 1987 and 2000 were used to investigate these changes. AutoCAD 2000, Arcview GIS 3.2 and Erdas Imagine 7.1 software were used. The results showed that land use in the Osse-Ossiomo River basin changed between 1970 and 2000. The built-up area is principally Benin City. As of 1965, the areal extent was about 25 km or 2500 ha, which increased to 645 km 2 or 64 500 ha in 1987, and 804 km2 or 80 400 ha by 2000. The other settlements, which included many villages of different sizes (ranging from 5 to 10 km), have merged with the Benin City metropolitan area. The number of roads has increased and the original tropical rainforest vegetation is now a more open type of guinea savanna vegetation.

It often also leads to loss of lives. In Lagos, urban flooding has largely become the focus of development initiatives. This paper examined the socio-economic impact and public perceptions of flooding in Lagos using questionnaire survey, personal observation, In-depth Interview (IDI) and Focus Group Discussions (FGD). The findings show that urban flooding has led to the damage of personal and public properties ranging from house utensils, foods, books to cars, buildings and schools. About 39% of the respondents have their economic activities affected by flood and the monetary value of loss in business due to flooding from single storm event range from $84.75 to $8474.58.

Aerial photography and Landsat multi-spectral imagery were used to assess the land use and land cover of the basin as it was in 1965 and 2005, respectively. Calculations of the area of various units for the two scenarios were generated. Overlay analysis for change detection in a matrix format was carried out. The change matrix was used to assess the extent of degradation. The statistic land cover of the lower Ogun flood plain in 1965 was 38.01 x 106 ha. The ecologically fragile wetland covered 82.45% of the total area. This figure decreases to 13 x 106 ha or 36.31% in 2005 at an average rate of 0.439 x 106 ha per annum. A conservation management approach to rescue the fragile ecosystem of the lower Ogun from complete destruction is proposed.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><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="66119268"><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="66119268"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 66119268; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=66119268]").text(description); $(".js-view-count[data-work-id=66119268]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 66119268; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='66119268']"); 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 (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=66119268]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":66119268,"title":"20.

The study on the rural communities of the southwestern parts of Anambra State of Nigeria illustrates the need for integrated management of water resources through advanced data collection and monitoring techniques, as well as local participation because the food security, health and well being of the people are at great risk.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><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="66119265"><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="66119265"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 66119265; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=66119265]").text(description); $(".js-view-count[data-work-id=66119265]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 66119265; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='66119265']"); 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 (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=66119265]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":66119265,"title":"Water resources challenges in Nigeria: pathways to water security and sustainability","internal_url":"https://www.academia.edu/66119265/Water_resources_challenges_in_Nigeria_pathways_to_water_security_and_sustainability","owner_id":51962856,"coauthors_can_edit":true,"owner":{"id":51962856,"first_name":"Lekan","middle_initials":"","last_name":"Oyebande","page_name":"LekanOyebande","domain_name":"unilag","created_at":"2016-08-11T12:20:39.723-07:00","display_name":"Lekan Oyebande","url":"https://unilag.academia.edu/LekanOyebande"},"attachments":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="66119126"><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/66119126/Water_resources_research_trends_and_needs_In_1997"><img alt="Research paper thumbnail of Water resources research: trends and needs In 1997" class="work-thumbnail" src="https://attachments.academia-assets.com/77436631/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/66119126/Water_resources_research_trends_and_needs_In_1997">Water resources research: trends and needs In 1997</a></div><div class="wp-workCard_item"><span>Hydrological Sciences Journal</span><span>, 1998</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">Scientific Committee on Water Research ou la dynamique des 茅cosyst猫mes aquatiques.

The major sources of surface water in the Sudano-Sahelian zone are the Lake Chad, K. Yobe-Hadejia, Sokoto-Rima and Gongola river systems. The seasonal and long-term variations in the flow of the rivers underline the importance of over-year storage as a means of making optimum use of the water resources. For example, most of the Sahelian rivers dried up during the 1973 and 1984 droughts, making the existing manmade reservoirs look like oases in the desert. The high rates of evaporation from the reservoirs, persistent droughts, faulty designs and operation of the multipurpose dams and reservoirs have often led to drastic reduction in the areas of wetlands and available water in downstream areas.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="c921f9537f37cffc5a46528826dd30d4" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":72212952,"asset_id":57196959,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/72212952/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="57196959"><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="57196959"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 57196959;

A number of socio-economic factors such as poverty, the population explosion and the lack of hydrological and ancillary data, are at the root of these problems. Droughts and climatic variability aggravate the vulnerability of the continent and make sustainable water resources development a real challenge. Inadequate levels and coverage of water services plague both urban and rural communities, with attendant health risks. The major problems are examined, including diminishing per capita freshwater resources, poor management and inefficient utilization, and lasting solutions are proffered. The conclusion is that the hydrological, engineering and social sciences have important roles to play in enabling African economies to overcome the acute and often devastating water problems confronting them now and in future decades.

Overlay analysis was used to carry out change detection which was presented in matrix format. The built up area is the dominant land cover for 1975, 1987 and 2005. The greatest expansion of the builtup area occurred between 1965 and 1975, during which it grew at the rate of 87.87 hectare per annum.

The major sources of surface water in the Sudano-Sahelian zone are the Lake Chad, K. Yobe- Hadejia, Sokoto-Rima and Gongola river systems. The seasonal and long-term variations in the flow of the rivers underline the importance of over-year storage as a means of making optimum use of the water resources. For example, most of the Sahelian rivers dried up during the 1973 and 1984 droughts, making the existing manmade reservoirs look like oases in the desert. The high rates of evaporation from the reser颅 voirs, persistent droughts, faulty designs and operation of the multi颅 purpose dams and reservoirs have often led to drastic reduction in the areas of wetlands and available water in downstream areas.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="3e2ea139fe3998fb0e30f8020c443e6e" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":77436672,"asset_id":66119277,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/77436672/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="66119277"><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="66119277"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 66119277;

Weekly water level measurements for 12 wells were carried out for dry season periods between November 1995-April 1996 and November 2007-April 2008. The drawdown arising from climate variability/change and urbanization impacts between 1995 and 2008 was estimated using overlay analysis and mapped as digital terrain model (DTM). Average annual drawdown rate of 0.07 m per annum was estimated with a general drawdown of 0.8 m in the groundwater table of the dry season. This resulted in low production of water in most wells during the dry season periods. Annual maintenance of the wells during the dry season becomes imperative and this infringes on the economic wellbeing of the people. A complimentary extension of the surface water distribution network to the area is recommended.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><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="66119276"><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="66119276"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 66119276; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=66119276]").text(description); $(".js-view-count[data-work-id=66119276]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 66119276; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='66119276']"); 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 (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=66119276]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":66119276,"title":"Variability of water table in high density low income groundwater utilization area in Lagos, Nigeria","internal_url":"https://www.academia.edu/66119276/Variability_of_water_table_in_high_density_low_income_groundwater_utilization_area_in_Lagos_Nigeria","owner_id":51962856,"coauthors_can_edit":true,"owner":{"id":51962856,"first_name":"Lekan","middle_initials":"","last_name":"Oyebande","page_name":"LekanOyebande","domain_name":"unilag","created_at":"2016-08-11T12:20:39.723-07:00","display_name":"Lekan Oyebande","url":"https://unilag.academia.edu/LekanOyebande"},"attachments":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="66119275"><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/66119275/Flow_simulation_in_an_ungauged_basin_using_digital_elevation_model"><img alt="Research paper thumbnail of Flow simulation in an ungauged basin using digital elevation model" class="work-thumbnail" src="https://attachments.academia-assets.com/77436712/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/66119275/Flow_simulation_in_an_ungauged_basin_using_digital_elevation_model">Flow simulation in an ungauged basin using digital elevation model</a></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">The rate of water withdrawal from both surface and groundwater has also increased dramatically in...</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 rate of water withdrawal from both surface and groundwater has also increased dramatically in the last two decades.

Notable inefficiencies and deficiencies in cash generation have compelled the Power Holding Company of Nigeria (PHCN) to rely on fuel subsidies and government subvention for funding of capital projects with the resulting ever accumulating energy supply deficits. Incidentally, the energy sector is one of the main drivers of GHG emissions, hence of global warming and climate change. It contributed 140% increase during 1970-2004 to the growth of GHG emissions. Climate variability and change caused reduced inflows into dam reservoirs resulting in the drastic and steady drop in the hydroelectric power generated by dams the Kainji and other dams in Nigeria between 1973 and 1994 and in 2003.

It often also leads to loss of lives. In Lagos, urban flooding has largely become the focus of development initiatives. This paper examined the socio-economic impact and public perceptions of flooding in Lagos using questionnaire survey, personal observation, In-depth Interview (IDI) and Focus Group Discussions (FGD). The findings show that urban flooding has led to the damage of personal and public properties ranging from house utensils, foods, books to cars, buildings and schools. About 39% of the respondents have their economic activities affected by flood and the monetary value of loss in business due to flooding from single storm event range from $84.75 to $8474.58.

Yet the Sahel wetlands are the lifelines for the inhabitants of the zone. The wetlands have many uses: for crop and grazing lands, fishing grounds and habitat for wildlife, and these multiple uses yield many products of water, food, fibres and energy.

Aerial photography and Landsat multi-spectral imagery were used to assess the land use and land cover of the basin as it was in 1965 and 2005, respectively. Calculations of the area of various units for the two scenarios were generated. Overlay analysis for change detection in a matrix format was carried out. The change matrix was used to assess the extent of degradation. The statistic land cover of the lower Ogun flood plain in 1965 was 38.01 x 106 ha. The ecologically fragile wetland covered 82.45% of the total area. This figure decreases to 13 x 106 ha or 36.31% in 2005 at an average rate of 0.439 x 106 ha per annum. A conservation management approach to rescue the fragile ecosystem of the lower Ogun from complete destruction is proposed.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><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="66119268"><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="66119268"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 66119268; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=66119268]").text(description); $(".js-view-count[data-work-id=66119268]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 66119268; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='66119268']"); 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 (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=66119268]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":66119268,"title":"20.

The major sources of surface water in the Sudano-Sahelian zone are the Lake Chad, K. Yobe-Hadejia, Sokoto-Rima and Gongola river systems. The seasonal and long-term variations in the flow of the rivers underline the importance of over-year storage as a means of making optimum use of the water resources. For example, most of the Sahelian rivers dried up during the 1973 and 1984 droughts, making the existing manmade reservoirs look like oases in the desert. The high rates of evaporation from the reservoirs, persistent droughts, faulty designs and operation of the multipurpose dams and reservoirs have often led to drastic reduction in the areas of wetlands and available water in downstream areas.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="c921f9537f37cffc5a46528826dd30d4" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":72212952,"asset_id":57196959,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/72212952/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="57196959"><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="57196959"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 57196959;
