Upgrading of a flood spillway - Confidential project (France)
Investigating the best solutions for increasing the flood capacity of the dam
Client: EDF - Scale: 1:40
Background
Artelia was contacted with a view to studying various developments aimed at increasing the capacity of the flood spillway while remaining below the maximum water level elevation.
Aim of scale model Scale model of reservoir and dam with additional spillway
Check the capacity of the components of the present spillway
Study the flow conditions
Test the capacity of two potential spillway configurations
Check the energy dissipation conditions with two different outlet chute solutions
Description of scale model Scale model of the additional spillway in form of P.K. Weir
Entire reservoir represented
Existing manoeuvrable gates and valves
Two types of additional development tested: fusegates and PK Weir
Two types of chute: smooth chute with flip bucket and stepped chute
