摘要：A numerical model of low frequency waves is presented. The model is based on that of Roelvink (1993), tout the numerical techniques used in the solution are based on so-called Weighted-Average Flux (WAF) method with Time-Operator-Splitting (TOS) used for the treatment of the source terms. This method allows a small number of computational points to be used, and is particularly efficient in modeling wave setup. The short wave (or primary wave) energy equation is solved with a traditional Lax-Wendroff technique. The model described in this paper is found to be satisfactory in modeling low frequency waves associated with incident wave groups.
