This report documents the modeling procedure used during the FY96 Joint Distributed Surf Zone Environmental Model Program. The approach of this program is to develop techniques that incorporate current state of the art, physics based numerical models to determine surf zone characteristic that are important to the modeling and simulation community. To test this proof of concept, a suite of models were identified and tested for Camp Pendelton, CA, during two 7 day periods in January and August 1995, in which data from the Coupled Ocean Atmosphere Mesoscale Prediction System (COAMPS) and the deep water wave model WAM, were available. Spectra describing the wave energy distribution in both frequency and direction were obtained from the Southern California Regional WAM model and specified on the offshore boundary of the STWAVE shallow water wave model. STWAVE was run to coincide with the time period of available WAM and COAMPS data. The Navy Standard Surf Model (NSSM) was run for the Camp Pendleton area for the same periods that WAM and STWAVE were run: 814 Jan and 1824 Aug 1995. A refraction zone depth grid was built from a 100-m resolution bathymetric data base. Inputs included COAMPS wind speed and direction, tide levels from tide tables, WAM spectra, and a landing zone based on a linear beach slope of 0.007. WAM, STWAVE, and NSSM model outputs described in this report are available to the Modeling and Simulation community through the Master Environmental Library.
