• In Tunisia, during the last two decades, hill lakes occupy an important place in national strategies and Water Conservation Soil (CES). Water erosion affects nearly 3 million hectares of agricultural land in Tunisia, and is a threat to the sustainability of small dams to mobilize surface waters, where the dominant economic activity remains agriculture. The objective of this study is to provide evidence for mapping and vulnerability to regionalize multifactor siltation of 26 small lakes located in Central Tunisia, along the Tunisian Dorsal to Cap Bon. Three classes of multi siltation vulnerability were distinguished: areas with low vulnerability (49.6%); areas with medium vulnerability (27.6%) and highly vulnerable areas (22.8%). This first draft map is a tool to help decision makers for the allocation of crop areas and sites that may contain socio-economic infrastructure on the one hand and used to planning strategies for the development and management of water resources and conservation of water and soil at the scale of small watersheds and other.
