| 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. |
