WebNote: The above equation is derived from the SCS Runoff Curve Number method described in detail in NEH-4, Hydrology (SCS 1985) and SCS TR-55 Chapter 2: Estimating Runoff. The CN can also be obtained graphically using Figure D.10.1 or from TR-55. Once a CN is computed, the time of concentration (tc) is computed (based on the methods http://54.243.252.9/ce-3354-webroot/ce3354book/_build/html/lessons/lesson06/CNmethod.html
