Modeling Swell, High Frequency Spreading and Wave Breaking

Abstract

My long-term goal is to contribute to understanding of the nonlinear dynamics of the wave sea surface excited by wind. Of particular interest to me is the role of such interaction in long-term prediction of wave amplitudes excited in rough seas. I wish to develop the phenomenological diffusion model of interaction of gravitational waves on water surface in presence of wind and viscosity. Motivation for development of such a model is the fact that numerical solvers based on Hasselmann kinetic equation for waves are time-consuming and hardly can be used for practical purposes. Numerical solver based on the diffusion model is expected to be at least three orders of magnitude faster.
