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
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
