N2 - Developments in computational modelling of storm waves propagating in the coastal surf zone and overtopping at sea walls and related structures is reported. The AMA-ZON suite of ID and 2D Plan shallow water models are used for the calculations. The models employ a modern Riemann-based upwind scheme in a finite volume form for use on boundary-conforming meshes. Sea wall structures are approximately represented using a steep bed slope. Breaking waves are modelled as steep moving fronts represented by bore waves. Comparisons with measured data show good agreement for sloping sea walls. Results are presented for the effects of wave obliquity on overtopping discharges including cases involving Mach stem formation. For vertical and recurved sea walls, an accurate model of wave breaking is required.
