Explanation of the Bankfull Cross-Sectional Area Exercise
To assess the Bankfull cross sectional area estimate extracted from the 9-207 data.
- Bankfull Discharge was given as 23,639 cfs
- Graphically, Bankfull Discharge of 23,639 cfs intersected the plotted data regression line at a Bankfull cross sectional area of approximately 6000 sq ft along the 9-207 data points and of approximately 7500 sq ft along the regressed data line.
- Mathmatically, Bankfull Discharge of 23,639 cfs inserted into the regression equation on the graph resulted in a Bankfull cross sectional area value of 7298 sq ft.
