Streamflow during the buoy deployments was generally lower than average. Streamflow measurements during buoy deployments on St. Clair River. Greater variation in water levels, however, was detected at upstream gauges than downstream gauges. Specifically, the standard deviation of water levels ranged from 0.12 foot at the Fort Gratiot gauge compared to a standard deviation of 0.05 foot at the Algonac gauge. Water level fluctuations along St. Clair River during buoy deployments.
All animations represent one minute of actual deployment time as one second of animation time.
The pixel coordinates of the scanned images were registered with positional information on the maps to facilitate plotting of measured buoy locations. Buoy locations were generally included at about 90-second intervals, when GPS data was available. Between measured locations, buoy positions were automatically interpolated by use of a Bezier curve. A Flash file reader plug in for standard Internet browsers is available without charge from Macromedia . Results Data on buoy deployments were animated to help visualize the flow pattern and turbulent dispersion characteristics near public water intakes on St. Clair River.
