Evacuation of Sediments from ReservoirsThis book is concerned with one of the methods of removing sediments from reservoirs, namely the flushing of sediments through purpose built outlet works within the dam. This technique can be applied to existing dams, with adaptation of the engineering works, and to new dams. The book gives practical guidance on the necessary hydrological, hydraulic, sedimentological and topographical features for successful flushing.In this book the author draws together his wealth of experience of working in this field. |
