  • Sedimentological and Lithostratigraphic Study of the Senonian Series in
           Timstiguite Region, Central High Atals, Morocco

    • Authors: Abdelouhed Farah, Ahmed Algouti, Abdellah Algouti
      Pages: 01 - 11
      Abstract: In this paper, we present the sedimentological, stratigraphic and paleogeographic aspect of the Upper Cretaceous red formations (Senonian series) of Timstiguite region (Central High Atlas of Morocco). The formations were measured bed by bed and sampled in a very detailed way. An exoscopic analysis of the quartz grains was carried out by a systematic prospecting of the grains relief and theirs surface characteristic, this led us to characterize their origin and consequently to determine the different paleoenvironnements. The clay sediments of these formations seem to be a favorable prospect in point of view: evolution of the clay and non-clay sediments in this central basin of the High Atlas will depend mainly on the conjugation of tectonic, eustatic, climatic and other influences. The senonian thickness is more important than other sub basins (Albban and Imider) where it shows a very reduced thickness. The Senonian of Timstiguite corresponds to a succession of detrital and evaporitic carbonate facies, which confirms a coastal depositional environment with passages of some periods of marine emersions.

  • Application of The Hierarchical Multicriteria Analysis Method to The Study
           of Water Erosion (South of Azilal, Morocco)

    • Authors: Abdelouhed Farah, Ahmed Algouti, Abdellah Algouti, Mohamed Ifkirne
      Pages: 12 - 22
      Abstract: This study aims to apply the process of the analytical hierarchy in geographic information system to the study of water erosion in the southern part of the Azilal region, Morocco. This method is an important tool to be used in the planning and management of natural risks; it has allowed us to obtain a multi-factorial sensitivity map to water erosion. This sensitivity map of erosive soil conditions in the study area shows that 6% of the area is (less) exposed to erosion risk while 85% of the mapped area is moderately exposed to erosion risk and only 8% of the mapped area is highly exposed to water weathering factors.  Visually, the high-risk zones correspond to the area around ‘’Oued Lakhdar’’ and its tributaries.
