2. Studies of environmental conditions

2.1 Hydrodynamic stability study

The hydrodynamic study was broken down into three sub-studies:

• definition and analysis of the 30-year return swell in the immersion zone to characterize the hydrodynamic movements inducing dimensional forces on the reef structure;

• analysis of the hydrodynamic stability of the reef under certain swell conditions, taking into account heave, slip and overturning criteria;

• analysis of water pressure forces on components for structural dimensioning.

The first step in the hydrodynamic study is the analysis of the swell plan, based on empirical swell data measured at Sète. The swell buoy database of the Candhis...
