Abstract

The analysis of wave-current interaction (WCI) in numerical wave tanks (NWTs) requires the simultaneous generation of a current velocity profile and free surface waves. This paper presents a novel approach to simulate the WCI using an impulse-source-based methodology together with a numerical beach implementation. Three additional terms are added to the momentum equation, to incorporate current and wave generation, as well as the numerical beach. The model components, i.e. wave and current generation, and WCI, are verified independently against two sets of reference data [1, 2]. The results show excellent agreement for the wave-only case, while for the current-only and thus WCI, some model weaknesses can be identified.
