The principal goal of this project is to improve our understanding of the physics interactions which govern the spatial and temporal evolution of surface waves in finite water depths. This will be accomplished through the Shoaling Waves DRI large-scale field experiment. However one term not measurable is the nonlinear wave-wave interaction which will be used to compute energy balance necessary for closure to the transport equation. The principal objective of this project is to investigate via numerical means the source term balance in shoaling waves. From field measurements obtained in the fall of 1999, and exact solutions to the Boltzmann integral, extensive examination of source term balances will be made. In addition to this, an effort will be made to analyze wave-bottom interactions from field and numerical studies, and the effects of depth-current induced spectral refraction.
