Abstract

The technique of sediments drawing by the sluices of draining can reduce the speed of sedimentation in reservoir of dam and consequently increase the time of life. It must be realised rigorously whereas it is not the case in the majority of the Algerian dams. It has then engendred important problems of management, and sometimes the stopping of the exploitation of the dam. The study of the mud concentration in different dams has permitted to observe a critical value for every type of mud, and to determine something like an "optimum of drawing off" where the suspension density permits the drawing off.
