Abstract

This work concerns the catchment area of Sidi Thabet which is a region of the lower valley of the Medjerda basin in Tunisia. Our aim in this study is to quantify the water erosion of the soil and to develop a management plan. The development of the sensitivity map to runoff has led us to estimate the coefficients of runoff, the volumes of the floods (of period of return 26 years) are estimated by the application of the Sokolovsky model. The specific erosion "Es" at all sub-watersheds is the same. Specific erosion is in equal to 2669,5 t/km²/year. The responsible factor of the risk of erosion in the study area is the maximum monthly rainfall which is 227.3 mm. This value has a return period equal at 26 years. The proposed and planified installations are defined based on the map of risk of erosion and existing structures hydraulic.
