Evaluation Of Urbanization And Impacts On Water Quality In Nottawasaga Bay Using An Integrated 3-D Modeling Framework, Venkat S. Kolluru, Shwet Prakash, Doug Hodgins

International Congress on Environmental Modelling and Software

The Lake Simcoe Region Conservation Authority (LSRCA) in partnership with the Nottawasaga Valley Conservation Authority (NVCA) has been interested in addressing the cumulative impacts of land use changes due to urbanization to two water bodies, the Nottawasaga River and Nottawasaga Bay. In order to assess these impacts, an Assimilative Capacity Studies (ACS) was planned for decision-making on land use. The ACS involved application of a comprehensive 3-D hydrodynamic and transport model called GEMSS®. The model was calibrated both for hydrodynamics (currents and drogue trajectories) and baseline water quality measurements. The model was then applied to simulate conditions which are representative …
