Description:
An optimized version of a multilayer Hansen type Hydrodynamical-Numerical (HN) model is presented and discussed here as the basis for the following experimental extensions and enhancements developed to more appropriately handle near-shore processes: Non-linear term extension to facilitate small-mesh studies of near-shore, including river inflow dynamics; Layer disappearance extension to enable appropriate procedures in tidal flat and marshy regions, as well as some down/upwelling cases; Thermal advection enhancement for treatment of thermal pollution cases by method of moments coupled with heat budget procedures for dynamic plume development experiments; Monte Carlo diffusion enhancement to deal with dispersion via statistical methods and comparison to the method of moments experiments. Extensive efforts were invested in determining reasonable and appropriate boundary conditions for both the basic model and the extended versions presented here.
