Report of the partner outcomes concerning methodologies for optimal management of hydropower reservoir operation and flood risk prevention_D3.6

Date: 1 December 2011

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

In this report the different legal aspects and methodologies for an optimal management of hydropower reservoir operation and flood risk prevention in the partnership countries are investigated and compared.
