Estimate Bankfull Cross-Sectional Area Exercise
Exercise ObjectiveTo estimate Bankfull cross sectional area given Bankfull Discharge data and the 9-207 geometric measurements.
Exercise ProcessForm 9-207 data can be used to plot a cross-sectional area to discharge relationship. You can either view the graph on this FGM Module page, or use Excel to view the relationship. In Excel, if you downloaded the completed workbook, the graph is already plotted. If you would like to create the graph, the Excel columns to use in the 9-207 worksheet are xsec_area and discharge.With the Bankfull Discharge estimated earlier, find the associated cross-sectional area. To get cross-sectional area, read the nearest graphical data point or use the shown equation.
