Abstract
A numerical model of nearshore waves, currents and sediment transport was developed. The wave conditions were calculated by the Modified-EBED model and the surface roller was modeled following the approach of Daily and Brown (1995) with an enhancement of the energy flux term in the alongshore direction. Nearshore currents and wave setup were determined by the depth-averaged momentum equations together with the continuity equation. Sediment transport rates in the offshore and surf zone were modeled based on the formulas of Camenen and Larson (2005) and the advection diffusion equation, whereas the swash zone transport rates were obtained by the formulas of Larson and Wamsley (2007).The model was validated based on the high-quality data from...

The present model will form the basis for predicting the bathymetric evolution in the nearshore due to waves and currents. (Less)
