Numerical investigation of bore hole filling volume in a coastal area
Résumé
We performed the coupling between a coastal circulation model and a discrete element model to investigate the parameters controlling the bore hole filling volume in Alderney Race. Simulations were carried out with spherical particles and considering monopile and tripod technologies. We show that: as long as the distance between the bore hole and the residuals remains smaller than twenty meters, the flow direction plays a negliglible role for the monopile case; the filling of tripod is strongly influenced by the flow and the seabed morphology; interactions between moving particles and bottom roughness lead to a slight increase of the filling.
