Project Description

The unique physical, chemical and biological characteristics of the St. Marys River, which is the outlet of Lake Superior connected to Lake Michigan-Huron downstream, provide for a rich and diverse environment that is a vitally important aquatic resource in the upper Great Lakes system. This project will involve developing an integrated ecosystem response model with simulated two-dimensional hydraulics (IERM2D) applied to the St. Marys River, and an initial prototype application of this model to the St. Marys Rapids area and calibrated/validated for a limited number of hydrologic scenarios. The project will include identifying critical objectives for the model and appropriate performance indicators; collection and documentation of all currently available data and models that could be used in support of this work; identifying gaps in this information and potential strategies and/or project that may be required; and development of a prototype version of the model for the St. Marys Rapids area. The model will be based on an existing 2D hydrodynamic model currently in development by USACE-Detroit and will have the potential to be extended to the full St. Marys River and a larger range of water supply scenarios).
