Abstract: During the International Joint Commission (IJC) Lake Ontario and St. Lawrence River Study, research was conducted to predict long term water temperatures in the Bay of Quinte. The purpose of this research was to study of the impacts of the water level management alternatives for Lake Ontario on the availability and quality of fish habitat. To evaluate the management options, water temperatures in the Bay of Quinte, were required over a 101-year period (1900 to 2001). A special hydraulic-temperature coupled model was developed using a one-dimensional hydrodynamic engine to derive the temperature model. The hydrodynamic model was developed earlier for the St. Lawrence River and was adopted for this study employing a double-sweep solution to the tree structured hydraulic system. The solution of the St. Venant’s unsteady flow equation was obtained by a finite element predictor-corrector method. The temperature model was based on temperature balance and conservation employing an explicit scheme. In order to simulate and predict water temperatures through out the Bay system, three types of data were acquired, reduced and employed in the model developed. First, bathymetry data were obtained and extracted to describe a cross-section and other geometric and resistance data for the one-dimensional hydrodynamic modeling. Second, discharge and hydraulic data were obtained and estimated from the flow records collected by the Water Survey of Canada, while the water level data for Lake Ontario were obtained from Canadian Hydrographic Service. Finally, air temperature data were obtained from information collected at Belleville. When air temperature data for the earlier period were not available, Toronto data were ported with a regression correction between Belleville and Toronto. The model was calibrated and verified prior to simulation for ice-free periods between April and November. Model calibration and validation were accomplished using water temperature data collected over a three-year period at six sites in the Bay of Quinte. The model showed the same trends as those observed reaching the critical temperatures for spring and fall spawning within the tolerance of the fish habitat model.
Description: Paper presented at The Seventh International Conference on HydroScience and Engineering (ICHE) hosted by the College of Engineering at Drexel Univeristy on September 10-13, 2006 in Philadelphia, Pennsylvania. The conference theme was IT in the Field of HydroSciences. It included several mini-symposia that emphasized IT topics in HydroSciences and the yearly meeting of the metadata group of the International Oceanographic Data and Information Exchange organization.
