Dams in operation

Existing dams are structures with very complex functioning for which the mobilisation of know-how and operational experience is essential in order to identify malfunctions and propose monitoring, operational, maintenance, analysis, diagnostics and strengthening actions to take.

 

Through its involvement in numerous projects, some of which are landmark, we have acquired excellent operational experience in the behaviour of materials and constructions (swelling and creeping in concrete, internal erosion, the behaviour of metals) which allows us to bring new dimensioning approaches to old constructions.

The Midi Hydroelectric Company asked ISL to produce a digital 3D hydraulic modeling of the spillway.
