Environmental Impact Assessment of the quarries on Grou River: Khenifra region- Morocco

Abstract

Abstract Khenifra region is rich in geological resources, which attracted a lot of investment, especially the quarrying. The Grou River watershed contains a lot of quarries of alluvial material extraction which causes negative impacts on its environment such as landscape modification, water quality degradation, dust emission and, soil erosion. The evaluation of water quality by measuring physicochemical parameters showed a deterioration of its quality in the downstream area compared to the upstream area. To respond to this situation, we suggest a set of mitigation measure and propose the respect of monitoring and surveillance plans.
