Assessment and propositions for strenthening sea defense structures in the Cotentin and Bessin Natural Park territory.

The Safety of Constructions

Of all civil engineering works, dam failure poses the highest potential risk of damage to life, property and the environment.  Dam security requirements are very strict and are present at every phase of the project: planning, design, construction and operation. Safety in the event of flooding or earthquakes, risk of instability in the foundations (internal erosion, liquefaction) - risk analysis and assessment are an integral part of our role as engineers.


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


This is an arch dam, 70m high, built at the end of the 1950s. A detailed diagnosis of the abutment led to envisaging strengthening works, by increasing its weight.
