Study on the mudbank stability of a reservoir

Modernization and maintenance of a dam often require emptying the reservoir, that can entail mud bank instability and environnemental disturbances. To characterize mud bank collapse, a study is led in partnership with the Laboratoire National d'Hydraulique (LNH), part of Electricite de France (EDF). This paper deals with geotechnical modelling of stability of immersed and emerged mud banks and with the comparison between model results and measurements performed in the whole reservoir.
