Abstract: The curve number runoff equation of the U.S. Department of Agriculture, Soil Conservation Service, is treated as a transformation from rainfall distribution to runoff frequency distribution. Reasonable agreement between observed and hypothesized result was obtained on four of the five watersheds shown. The hypothesis failed for the watershed tested in the arid southwest.
