Modeling and quantification of hydro-sedimentary flow of risk areas in the catchment of wadi chemorah, wilaya of batna, algeria

Abstract

This work is a comparative study of water erosion and suspended sediments in the two hydrometric stations timgad and reboa belonging respectively to of Wadi Soulrez and Wadi Reboa, located in the North-East of Algeria. The approach adopted for the quantification of sediment transport consists on researching the best regressive model to represent the statistical relation between the sediment yield and the measured water discharge at different scales: annual, seasonal and monthly. The available data cover 27 years from 1985 to 2012.
