Dynamic operation of hydro power plants for flood prevention and desiltation_D3.5

Date: 1 December 2011

Sedimentation processes are balanced in most of the natural rivers. The construction of dams and reservoirs influences this balance. In reservoirs the flow velocities, turbulences and bed shear stresses are reduced and this leads to sedimentation of the transported bed and suspended load. In further consequence the bed levels rise and reduce the storage volume by “filling up” the reservoir (Harb et al, 2010). Decreased reservoir volume reduces and - in extreme cases - eliminates the capacity of hydropower production, water supply, irrigation and flood control benefits (Morris & Fan, 1998).
