Swan
SWAN is a third-generation wave model for obtaining realistic estimates of wave parameters in coastal areas, lakes and estuaries from given wind, bottom and current conditions. The model is based on the wave action balance equation with sources and sinks. SWAN allows to use two types of grids (structured and unstructured) and nesting approach. SWAN is not recommended to use in on ocean scales.
Manual can be found here and more about SWAN settings can be found here.
