Sedimentary State of the Middle Sebou Valley, Between Oued Inaouene and Oued Bouchabel (Pri- Rif) - Morocco

Abstract

In this paper, we will study the sedimentary state of the river Sebou, which extends between the Mesopotamia, Inaouene Valley and Bouchabel Valley, which is an area of about 36 km (Figure 1). We will analyze the sedimentary components at the bottom of the oued and the level of the floodplain through the banks of the latter. This area comes directly after the confluence of Oued Sebou with Oued Inaouene, in the area of Hamria in douar Ben Hadan, as it extends to the western borders of the center of Sidi Daoud, downstream of the bridge of Sebou in douar Oulad Ben Hamou, where the Oued Sebou takes a general direction from southeast to northwest. This course draws free river confluences in the floodplain extending to the bottom of the Sebou Valley, which is surrounded by land dominated by clay hills of different heights, and overlooking the valley with long to medium slopes. In our study, we relied on fieldwork, including field observation, identification of sections to be studied and analyzed, determination of the properties of river sediments, including coarse elements and morphometric analysis of the gravel, and we relied on choreographic work to draw crosses. Sections and we worked on the identification of the types of banks and the nature of its sedimentary components, we studied the volume of coarse sedimentary elements, in addition to the study of fine sedimentary materials, including laboratory analysis of micro-sediment grains, and we worked on the morphoscopic analysis of quartz grains.
