Abstract

This work presents a description of partial wave reflection and transmission effects for rubble mound structures using time dependent depth averaged equations of the type used in a Boussinesq non linear wave model and in a hyperbolic linear wave model. Energy losses due to friction effects on the rough slope of a rubble mound structure can be represented using a friction area in front of a vertically faced homogeneous porous structure. The flow resistance within the structure is simulated in a similar way by incorporating an additional term in the momentum equation given by a Dupuit-Forchheimer relationship. 1. Introduction Pre
