1. Preliminary studies

Before undertaking the final siting and construction of a wave protection structure, it is necessary to have a thorough knowledge of the site's characteristics and local resources, so as to create a structure that is optimized according to the fundamental criteria of :

• sustainability;

• the effectiveness of wave protection ;

• construction costs ;

• maintenance costs.

Indeed, given the very high cost of this type of structure, their desirable lifespan is at least 50 years, and often reaches several centuries.

In general, the information gathered during the preliminary study phase is sufficient to determine the location of the harbor and the characteristics of its main wave protection structures,...
