Locate Reach

Function

This command places a reach on a flow polyline of the watershed schematic for TR-20 Hydrograph Development. The program prompts for the reach length, end area coefficient and exponent M. These variables are explained in the TR-20 manual. A square reach symbol that contains the reach data is drawn on the flow polyline. The reach labels show the length above the end area coefficient and exponent M.
