Abstract

Numerical simulations on the wave overtopping phenomena were carried out for double seawalls with permeable bottom by using the numerical model of CADMAS-SURF. The double seawall consists of lower front and higher rear walls and permeable bottom between the two walls. The present paper has proposed the selection procedures for the optimal cross-section of the double seawall. The optimal cross-section can reduce the crown height of the double seawall. Consequently the double seawall is effective on the preservation of landscape.
