This paper examines the effect of current-induced breaking on the modeling of wave breaking dissipation near rip currents. Simulations using a set of existing wave transformation models are compared to existing laboratory measurements made on a bar/channel topography in the presence of both strong and weak rip currents. The model/data comparisons demonstrate that existing models can effectively...

A mathematical model is presented for calculating the change in volume and sand-bypassing rate at ebb-tidal shoals. Conceptually and mathematically, the ebb-tidal shoal is distinguished from bypassing bars that emerge from it and from attachment bars where the bypassing bars merge with the beach. The volumes and bypassing rates of these morphologic entities are calculated by analogy to a reserv...
