Details of modeling approach for developing estimates of design water levels and waves for two U.S. Army Corps of Engineers USACE Buffalo District repair projects are described in this report. The estimates are for 1 the existing Buffalo Harbor BH South Breakwater SB and its two repair alternatives, and the existing BH North Breakwater, and 2 the LaSalle Park seawall along the northeast shore of the harbor that connects to the Niagara River canal. Two classes of wave models were used to develop these estimates for structural repairs 1 CMS-Wave, a spectral wind-wave generation, growth, and transformation model, and 2 a nonlinear Boussinesq-type wave model BOUSS-2D. Estimates were developed for the 10-year maximum design water level condition of 3 meters m 9.8 feet ft Low Water Datum and the 20-year design storm conditions with incident wave heights of 3.85 m 12.6 ft and 4.15 m 13.6 ft, peak period of 10 seconds, and three incident wave directions of 233, 240, and 247 degrees. Study details, including data used, numerical modeling investigations, and analysis of results, are presented in this report.
