干旱区生态环境知识资源中心

Erosion and solid transport processes in the basins of Mediterranean semi-arid zones have interested a great number of hydrologists, whose studies have increased in the last ten years with the aim of understanding and explaining the mechanisms, their causes and their consequences. In this context, we attempt to show, by means of in situ measurements, the relationship between water discharge and sediment discharge. A statistical model was developed using water discharge data of selected floods. The results obtained at Mekerra station (Sidi Ali Benyoub, Algeria) are very encouraging, as the coefficients of correlation of both annual and seasonal water discharge to sediment discharge vary from 0.90 to 0.91.
