Abstract:

The sediment-contaminant transport code, FETRA, coupled with the hydrodynamic model, CAFE-I; and the wave refraction model, L03D; were applied to Pacific coastal water. The FETRA model simulated wave-induced transport, deposition, and resuspension of cohesive and noncohesive sediments in coastal water including the surf zone. The model also calculated changes of bed conditions, such as bed elevation changes caused by bed scouring and sediment deposition, and bed sediment size distributions. Predicted sediment distributions were found to be in reasonable agreement with an observed general pattern.
