Abstract:

The GLERL-Donelan parametric wave model and the SHALWV spectral wave model are presently being used as modules of the Great Lakes Forecasting System in order to determine which best fits the system's aims and limitations. Idealized benchmark tests and Lake Erie lake-wide and nearshore hindcasts are being used for model evaluation. Results indicate that SHALWV's features are likely to be of benefit near coastlines and with storms containing turning winds. The model would however benefit from being tuned to Great Lakes data. If SHALWV is run on a main lake-wide grid, with nearshore sub-grids, computational requirements may be manageable.
