Abstract: A multi-scale parallelised coupled model is developed to investigate wave-current interactions at regional scales. The coupled framework consists of the spectral wave model Simulating WAves Nearshore (SWAN) and the coastal hydrodynamics shallow-water equation model Thetis. The coupling process is facilitated by the Basic Model Interface (BMI). In this study, we assess the model’s ability to accurately capture wavecurrent interactions in a 2-D configuration through the simulation of Dingemans (1987) experimental setup on the behaviour of waves acting upon a submerged bar. The coupled model accurately captures the significant wave heights and the current velocities showcasing a similar level of efficiency as another coupled wave and 3-D current model presented by Roland et al. (2012).
