Simulation of Solid Transport from the Sub-watersheds and Hydrometrics Stations in the Catchment Area of the Wadi of Hammam (Algeria)

Abstract

Deductions are an essential part of managing water resources in semi arid. Their protection against filling with sediment resulting from erosion of upstream watersheds is essential to ensure the profitability of these investments. The violence of water erosion on the catchment area of the wadi of Hammam as'[9] explains mainly by the presence of marly terrain, high rainfall intensities, runoff concentrated on steep slopes and vegetation almost not exist. The actual study of the phenomenon at different gauging stations is the subject of our study concerns the assessment of suspended sediment from the liquid-flow A relationship strong flows during the period of 20 years. Using the regression method in the evaluation, the power regression model was retained, while allowing to homogenization, quantification and hence the calculation of the specific erosion by two methods: the use of average flows monthly and instantaneous flow.
