The goal of the sand modeling effort is to provide a validated predictive capability for the propagation of shock waves through the surf zone SZ environment of water, sand, and entrained air. Since the details of the physics are included in the model, this tool is also capable of modeling the response of the threat mine structure to the shock wave. Previous SZ explosive mine countermeasures MCM systems experimental data have indicated that explosive shock waves were highly attenuated when propagating through the sand bottom. The rate of attenuation was determined to be sensitive to the saturation level and skeletal characteristics of the sand bottom. Because of environmental limitations, all explosive testing in the United States for the SZ MCM project has been conducted in artificial test ponds. It has been recognized that the bottom conditions in man made test ponds do not necessarily represent natural beaches therefore it is essential to have a methodology to relate test pond results to real world beaches.
