Abstract
The nonlinear shallow water equations can be used to model broken waves within the surf and swash zone. Here we detail the development of several numerical schemes that have been taken from gas dynamics and adapted for use in the surf zone. The numerical schemes can be applied in one or two horizontal dimensions, they have the advantage over shallow water models used at present that they are faster and more accurate.
