K.G. RANGA RAJU: SEDIMENT MANAGEMENT IN HYDROELECTRIC PROJECTS
Abstract: Withdrawal of water from a river into a canal
involves the construction of a barrage or a dam across the river
depending on whether the river is perennial or not. The design of the
reservoir upstream of the dam and of the canal requires consideration of
the sediment load carried by the river in case the river is
sedimentladen. The basic equations concerning morphological changes in
such rivers are discussed with particular reference to computation of
reservoir sedimentation. The hydraulics of lined canals carrying wash
load is examined from the point of view of limiting transport capacity
and changes in frictional resistance. Lastly, the methods of design of
sediment extraction devices like settling basins and vortex chambers are
presented.
