Improved St. Clair River Dynamics Flow Models and Comparison Analysis

摘要

The St. Clair River dynamic flow models, modified to provide better channel definition, to include additional discharge measurements for model calibration, and to incorporate wind stress effects on river flows, are described and compared for daily flow differences resulting from channel definition improvements, wind effects, time scale effects, and a combination of these factors. All the St. Clair River models are derived for the upper river channel, spanning approximately one-third of the river. The three available models can be operated on hourly or daily time scales, with and without surface wind stress effects. During the winter, ice may affect the accuracy of flow computations and model differences may exceed 15% of daily flow.
