DOI: 10.1016/j.ocemod.2017.06.012
Abstract: Wave-induced currents are an ubiquitous feature in coastal waters that can spread material over the surf zone and the inner shelf. These currents are typically under resolved in non-hydrostatic wave-flow models due to computational constraints.… read more here.
