Different approaches to model the nearshore circulation in the south shore of O'ahu, Hawaii

"The dynamical interaction between currents, bathymetry, waves, and estuarine outflow has significant impacts on the surf zone. We investigate the impacts of two strategies to include the effect of surface gravity waves on an ocean circulation model of the south shore of O’ahu, Hawaii. This are...
