Wind and wave characteristics in Lake Erie, which is one of 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, which means predominance of wind waves during this period in Lake Erie. Wave hindcast using BRTM (Backward Ray Tracing Model) is conducted under the same bathymetry and wind input conditions as Lalbeharry et al. (2000), which were kindly provided by Dr. R. Lalbeharry, Canadian Meteorological Service. Intercomparison among BRTM-based wave data, WAM-based wave height data given by Dr. R. Lalbeharry 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.
