Abstract:

The model is a two-dimensional discrete, time dependent, arbitrary depth spectral wave model. It simulates the growth, decay and transformation of a wave field over a spatial area such as on ocean basin, a bay, a continental shelf or a lake over a period of time. SHALWV is intended to provide hindcasts of wave climates or specific storms or simulation of idealized events like a standard project hurricane. Most importantly it can accommodate realistic bathymetry. The computer program is based on the solution of the inhomogeneous energy balance equation solved via finite difference methods utilizing a square grid mesh describing the bottom topography and also a wind field. The field equation represents the following mechanisms wind-wave growth, refraction, shoaling, nonlinear wave-wave interactions, wave bottom interactions bottom friction and percolation, high frequency energy dissipation, surf-zone breaking and the decomposition of the energy into wind-sea and swell wave components.
