Explanation of the Bankfull Discharge Exercise
To assess the Bankfull Discharge estimate extracted from the 9-207 and WATSTORE stage-discharge relationship.
- Bankfull stage was given as 22 ft
- Graphically, Bankfull stage of 22 ft intersected the plotted data regression line at a Bankfull Discharge of approximately 24,000 cfs along the Annual Peak data line from the WATSTORE dataset.
- Mathmatically, Bankfull stage of 22 ft inserted into the regression equation on the graph resulted in a Bankfull Discharge value of 23,639 cfs.
