Development of a Coupled Coastal Dynamic Model Phase I: a New Numerical Coastal Wave Modeling

Numerical and analysis was used to identify the best code, which is then used to test pure propagation of swells in a coastal region. Furthermore, we have also coded the four wave interaction computation in the nonlinear source function based on the Zakharov formulation. Though the final form still does not have a Homiltonian structure, the formulation resulted in a great reduction of computation time. Additional investigation into the higher order (five-wave) interaction was also conducted.
