A. Boualem1 2University Center Stambouli Mustapha of Mascara, Algeria ABSTRACT Following increased degradation of the vegetation cover on the upstream watershed, reservoir sedimentation remains a major problem in northern Algeria, with the main factor being sediment in runoff whose spatial distribution is controlled by precipitation, lithological characteristics and physiography. The western part of the country is the most affected, followed by central and eastern areas. The erosion loss ranges from 20 to 40 t/ha/yr with a rate of silting often exceeding 15%. Algeria is one of the countries most threatened in the world by this phenomenon. The objective of this study is to show the rate of silting in the Bouhanifia Dam in western Algeria, and to analyze the consequences. The results were used to classify the dam among the most endangered, having reached a level of unprecedented silting. Priorities are also defined for removing sediment and reducing erosion within the scope of a sustainable development policy. Reference: Boualem, A., M. Larid, and K. Mederbal. 2009.
