Abstract

We compare two recently developed sets of source terms, based on different assumptions of wave energy input and dissipation, for Hasselmann equation. The numerical simulation, performed for limited fetch conditions with the constant wind speed shows the difference in total energy and mean frequency distributions along the fetch as well as in wave energy spectra. Possible reasons of such deviations are offered.
