Fractured rocks influence on hydrological flow in of the Agourai plateau, Middle Atlas, Morocco: Inferences from Isobase lineaments and field data

Abstract

This study provides new data of hydrological flow direction in the Agourai plain, Tabular Middle Atlas, north central Morocco. Given its major economic interest in term of agricultural production, the analysis of fracture networks remain essential for a good management of water resources. Mapping fractures network, using isobase maps combined with field data reveal three groups of fractures oriented N-S, NE-SW and NW SE. the latter was poorly described and lies with the setting of three main springs in the area. Fractures analysis in the Bouchermou spring, confirm the predominance of NW direction, which control of the water flow in this area.
