英文摘要	Water erosion is one of the most severe environmental problems, especially in arid and semi-arid regions. It is responsible for soil loss and degradation of ecosystems. This study is interested in mapping water erosion hazard (WEH) in the Chaffar Watershed (Southeastern Tunisia), using analytical hierarchy process (AHP) and fuzzy logic modeling. The importance of major factors affecting erosion (field slope, soil lithology, vegetation index, land use, and rainfall) was inspired from a review of the literature, field investigations, and experts' knowledge. Water erosion conditioning factors and their spatial distributions were evaluated in a geographic information system (GIS). Water erosion hazard maps, simulated by AHP and fuzzy logic, were validated by field observations and Sentinel-2 satellite images. The resulting erosion hazard maps were found to be compatible with the results derived from the Sentinel-2 images. The receiver operating characteristic (ROC) curve validation result shows that, compared to the AHP model (AUC=84.7%), the fuzzy logic model (AUC =90.5%) predicted slightly better water erosion in the Chaffar Watershed. Generally, a moderate hazard of water erosion was found throughout the study watershed. The area characterized by a high to very high risk of water erosion was estimated to be 25% and 32% using fuzzy logic and AHP methods respectively. Highly eroded areas, which are quite limited, require immediate action.
