Abstract


The research carried out as part of this work aims to provide answers to the rhythms and processes of sedimentation in the lake of the Foum El Gherza dam. Based on the bathymetric surveys carried out by the National Dams Agency in the Foum El Gherza dam, we have shown the temporal evolution of the silting up of the dam. As a result, the filling of the lake exceeded 70% of its initial capacity as of 2007. Despite the de-silting of the dam by dredging, the dam is in critical condition. Dredging operations must continue in the short term to extend the life of the structure.


Keywords
