Abstract

Artificial reefs have been used to protect coastal erosion, and are now replacing detached breakwaters. Although constructions of the artificial reefs sometimes cause significant score around the reefs, the manuals for the design describe mainly on wave decay. An opening between artificial reefs shows typical scouring likea corn at the offshore of the middle of the opening. To estimate a topographic change, we need the distributions of water surface elevation and the bottoms currents.<BR>In this research, we investigated the ability of a fully nonlinear Boussinesq model around anopening with the eddy viscosity model for wave breaking. This paper shows that the numerical results have good agreement with experiments wave surface distributions and bottoms currents.
