Abstract: Monthly and annual direction distribution tables for significant wave heights and significant periods have been prepared for the west-southwest through the north to the northeast in 22.5-deg segments using hindcast data for Cleveland, Ohio, developed by A. H. Glenn and Associates of New Orleans, Louisiana. The significant height-significant period tables in the hindcast were used to distribute linearly the significant period over the monthly and annual percentages of occurrence of significant wave heights from each of the specified directions. The tables are given in Appendix A of this report. Refraction diagrams for 4-, 6-, and 8- sec waves near Cleveland are also included in this report. The initial starting point of the wave orthogonals on the refraction diagrams is approximately 3 miles offshore where the wave hindcast in the basic report is applicable. The results of the refraction analysis indicate that 4- and 6-sec waves are relatively unaffected by refractive effects except near the shoreline, but that the bottom topography may affect the direction of propagation of longer period waves from directions which are not approximately perpendicular to the lake bottom contours. Calculated monthly and annual net longshore wave energy is estimated for 15 locations along the Lake Erie shoreline near Cleveland. The longshore energy is variable along the shoreline, but a general eastwardly net longshore direction for the wave energy is indicated by the longshore wave energy data near Cleveland. Comparison of estimated and observed noncohesive longshore transport at two sites near Cleveland with results of this study indicates that shoreline composition, geometry, and protective structures have a significant effect on longshore transport near Cleveland. An estimate for the average annual total longshore energy is given.
