Abstract: The aim of this work is hydrological study and quantification of solid suspended transport in Mekerra basin which is located in the northwest of Algeria, in order to understand and explain the mechanisms of sediment, their causes and their consequences. The quantitative and qualitative analysis of the liquid flows and solid flows measured at this representative basin over a period from 1988-2009 (station: Sidi Bel Abbès) has revealed relations between the solid transport of wadis and their streamflow, in fact average specific degradation is 117 t/km²/year. The relations of the concentrations-liquid flows through the use of hysteresis curves have made it possible to identify the main classes of evolution. The curved shape in eight forms seems to be the most frequent. It reflects instantaneous erosive action and transport of rapidly suspended sediments caused by short showers, violent on generally dry, fragile and poorly protected soils.

Keywords: hydrological study; quantification of solid suspended transport; classes of evolution; sediment; Sidi Bel Abbes; Algeria.
