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

It is a function of land use, soil type, and soil moisture. The Natural Resources Conservation Service (NRCS) has divided soils into four hydrologic soil groups (i.e., A, B, C, and D) according to water’s ability to infiltrate.
