INTERCOMPARISON OF WAVE DATA HINDCAST IN LAKE ERIE

Wind and wave characteristics in Lake Erie, the Great Lakes are investigated based on the analysis of measurement data at 3 buoy stations over one month from October 22 to November 22, 2000. Relation between dimensionless wave height and wave period data is approximated by Toba's 3/2 power law with a slightly smaller coefficient. Wave hindcast using BRTM (Backward Ray Tracing Model) is conducted under the same bathymetry and wind input conditions as those used by Lalbeharry et al. Intercomparison among BRTM-based wave data, WAM-based wave height data and measurement wave data shows that BRTM yields as close an agreement with measurement data as does WAM and that error statistics may suggest a slightly higher estimating ability of BRTM over WAM.
