The dynamics associated with the formation of the Rif chain (Alpine tectonics), is accompanied by instabilities essentially related to tectonic movements. The realization of important infrastructures (Roads, Highways,...) represents a triggering factor and favoring landslides. This paper is part of the establishment of landslides susceptibility map and concerns the mapping of unstable areas in the province of Taounate. The landslide was identified using the components of the false color (FCC) of images Landsat OLI: i) the first independent component (IC1), ii) The main component (PC), iii) Normalized difference index (NDI). This mapping for landslides class is validated by in-situ surveys. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=landslides" title="landslides">landslides</a>, <a href="https://publications.waset.org/abstracts/search?q=False%20Color%20Composite%20%28FCC%29" title=" False Color Composite (FCC)"> False Color Composite (FCC)</a>, <a href="https://publications.waset.org/abstracts/search?q=Independent%20Component%20Analysis%20%28ICA%29" title=" Independent Component Analysis (ICA)"> Independent Component Analysis (ICA)</a>, <a href="https://publications.waset.org/abstracts/search?q=Principal%20Component%20Analysis%20%28PCA%29" title=" Principal Component Analysis (PCA)"> Principal Component Analysis (PCA)</a>, <a href="https://publications.waset.org/abstracts/search?q=Normalized%20Difference%20Index%20%28NDI%29" title=" Normalized Difference Index (NDI)"> Normalized Difference Index (NDI)</a>, <a href="https://publications.waset.org/abstracts/search?q=Normalized%20Difference%20Mid%20Red%20Index%20%28NDMIDR%29" title=" Normalized Difference Mid Red Index (NDMIDR)"> Normalized Difference Mid Red Index (NDMIDR)</a> </p> <a href="https://publications.waset.org/abstracts/73841/use-of-landsat-oli-images-in-the-mapping-of-landslides-case-of-the-taounate-province-in-northern-morocco" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73841.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">290</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Modeling of the Effect of Explosives, Geological and Geotechnical Parameters on the Stability of Rock Masses Case of Marrakech: Agadir Highway, Morocco</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Taoufik%20Benchelha">Taoufik Benchelha</a>, <a href="https://publications.waset.org/abstracts/search?q=Toufik%20Remmal"> Toufik Remmal</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachid%20El%20Hamdouni"> Rachid El Hamdouni</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamou%20Mansouri"> Hamou Mansouri</a>, <a href="https://publications.waset.org/abstracts/search?q=Houssein%20Ejjaouani"> Houssein Ejjaouani</a>, <a href="https://publications.waset.org/abstracts/search?q=Halima%20Jounaid"> Halima Jounaid</a>, <a href="https://publications.waset.org/abstracts/search?q=Said%20Benchelha"> Said Benchelha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> During the earthworks for the construction of Marrakech-Agadir highway in southern Morocco, which crosses mountainous areas of the High Western Atlas, the main problem faced is the stability of the slopes. Indeed, the use of explosives as a means of excavation associated with the geological structure of the terrain encountered can trigger major ruptures and cause damage which depends on the intrinsic characteristics of the rock mass. The study consists of a geological and geotechnical analysis of several unstable zones located along the route, mobilizing millions of cubic meters of rock, with deduction of the parameters influencing slope stability. From this analysis, a predictive model for rock mass stability is carried out, based on a statistic method of logistic regression, in order to predict the geomechanical behavior of the rock slopes constrained by earthworks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=explosive" title="explosive">explosive</a>, <a href="https://publications.waset.org/abstracts/search?q=logistic%20regression" title=" logistic regression"> logistic regression</a>, <a href="https://publications.waset.org/abstracts/search?q=rock%20mass" title=" rock mass"> rock mass</a>, <a href="https://publications.waset.org/abstracts/search?q=slope%20stability" title=" slope stability"> slope stability</a> </p> <a href="https://publications.waset.org/abstracts/71665/modeling-of-the-effect-of-explosives-geological-and-geotechnical-parameters-on-the-stability-of-rock-masses-case-of-marrakech-agadir-highway-morocco" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71665.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">376</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Landslide Susceptibility Mapping: A Comparison between Logistic Regression and Multivariate Adaptive Regression Spline Models in the Municipality of Oudka, Northern of Morocco</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Benchelha">S.

From spatial database containing data such as landslide mapping, topography, soil, hydrology and lithology, the eight factors related to landslides such as elevation, slope, aspect, distance to streams, distance to road, distance to faults, lithology map and Normalized Difference Vegetation Index (NDVI) were calculated or extracted. Using these factors, landslide susceptibility indexes were calculated by the two mentioned methods. Before the calculation, this database was divided into two parts, the first for the formation of the model and the second for the validation. The results of the landslide susceptibility analysis were verified using success and prediction rates to evaluate the quality of these probabilistic models. The result of this verification was that the MarSpline model is the best model with a success rate (AUC = 0.963) and a prediction rate (AUC = 0.951) higher than the LR model (success rate AUC = 0.918, rate prediction AUC = 0.901). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=landslide%20susceptibility%20mapping" title="landslide
