Abstract
Water erosion represent a major problem that has several negative effects. Soil degradation and loss, that will be transported later, cause in most cases remarkable and sometimes dangerous damage by destroying several structures. Faced with the continuous development of the causes that aggravate this phenomenon, mainly problems linked to climate change, the assessment and determination of areas affected by erosion has proved to be fundamental, in order to define the impacts and reduce the risks and prevent consequences. For this purpose, the study of the main morphological, geological, lithological, hypsometric, hydrological and climatic characteristics of the Assifel Mal watershed located in the middle of the High Atlas Mountains, will allow using geographic information systems and remote sensing to map areas with high erosive potential and their relationship with the distribution of factors involved. In addition, to define the risks associated with the existence of this phenomenon in the region, especially in the presence of human activity, which amplifies the danger.
