This paper presents the application of new source terms in SWAN for the dominant water wave physics in the coastal zone: depth-induced breaking and triad wave-wave interactions. We present results demonstrating increased modelling skill in the prediction of bulk wave parameters e.g. significant wave height and of the spectral shape compared to currently used defaults, particularly in cases with horizontal bathymetries. These preliminary results suggest a greater range of applicability of these source terms for operational applications.
