Description
Summary:This report describes the implementation of two new physics routines in the phase-averaged model for wind-generated surface gravity waves, WAVEWATCH III. The first routine accounts for the attenuation of waves by sea ice. The second routine accounts for the attenuation of waves by a viscous fluid mud layer at the seafloor. No such routines existed previously in this model, though the model did previously represent the partial blocking/transmission of waves by sea ice via the model's propagation routines. Results from simple one-dimensional and two-dimensional tests are presented. Planned future improvements for the wave-ice physics package are given. The original document contains color images.
