Webb10 maj 2011 · The standard SCS/NRCS rainfall distributions are commonly used for everything from 1-year to 500-year events. However, with wider availability of local Precipitation Frequency Data from NOAA, NRCC, and other sources, there is growing interest in generating local synthetic rainfall distributions based on the local PFD data.

Dimensionless Depth: SCS Distributions
WebbThese include: a) uniform rainfall (as in the Rational Method), b) the Chicago hyetograph, c) the SCS design storms, and d) Huff’s storm distribution patterns. Uniform Rainfall The simplest possible design storm is to assume that the intensity is uniformly distributed throughout the storm duration. WebbThis XML file provides the six regional rainfall distributions for California (CA-1 through CA-6) developed by NRCS to replace the SCS Types I, IA and II distributions used previously. The rainfall distribution values were taken from the February 2013 tables provided by NRCS for use with WinTR-55. For instructions, see How to create storm ... Webbusing the four SCS standard rainfall distributions. The original kinematic wave equation included rainfall intensity as a variable. Several studies were done to develop a relationship between the standard design rainfall distribution, 24-hr rainfall amount, and maximum hourly intensity. roadshow revival
