Lake St. Clair is a shallow water body located between Lake Huron and Lake Erie in the Great Lakes complex with coastline in both US and Canada. The numerical modeling of waves and water levels was performed to capture storm conditions along the US coastline. The methodology presented in Jensen et al. 2012 for Lake Michigan was followed for the majority of the project. The NOAANCEP Climate Forecast System Reanalysis wind fields were adjusted for marine exposure wind speeds. The WAM wave model was validated and applied for production of all wind generated wave results, including ice when applicable. The ADCIRC model was forced with wind fields, flow rates at the St. Clair River boundary, and water levels at the Detroit River boundary and validated to water levels at St. Clair Shores and Windmill Point. The ADCIRC model was tightly coupled with four near-shore Full-Plane STWAVE model grids using CSTORM-MS. The results show good agreement between all validation data sets, and low errors in the production storms with which data was available. In total, 145 storm events were run with the full numerical system to quantify the water level response to extreme events In Lake St. Clair.
