Authors : Remini B . Toumi A .

Abstract

In arid and semi-arid regions such as Algeria, siltation is a hydraulic problem which poses enormous problems to managers of dams including the reduction in capacity. This article discusses the silting of the Beni Haroun Reservoir who considered the largest Algerian dam. Based on the first conducting bathymetric survey in 2013, a volume of mud is 118 million m3 were deposited during ten years of operation, an annual rate of siltation of 1.2% / year. The Beni Haroun Reservoir is ranked among the most threatened by the phenomenon of silting of dam. In this case, the dam cannot reach one century an operating; a very short time for a large dam. Priority will be given to desalting of dam.
