Hydrodynamic Modelling of In-Stream Hydrokinetic Turbines in the St. Clair River

Thierry Faure;
This project assessed the hydrodynamic impacts of operating hydrokinetic turbines in the St. Clair River using a two-dimensional TELEMAC hydrodynamic model. Suitable locations and turbine types in terms of their ability to raise water levels and produce hydropower were explored. Hydrokinetic turbine operations modify the river's flow pattern and remove flow energy causing the hydrodynamics of the river to adjust to compensate for the changes. This compensation will be in the form of a rise in water level upstream of the turbines with the amount depending on number of turbines and their location. In addition to estimating energy potentially harvested from the river, this investigation also examined how different configurations of turbines affect levels and flows. It was found that while such turbines could be used to raise Lake Michigan-Huron water levels, but the effect is dependent on their size, number and placement in the river, which may conflict with other uses.
