A procedure was developed for estimating the frequency of storm runoff of various magnitudes from rainfall and/or snowmelt on small drainage basins in various stages of urbanization. The study was based primarily on the analysis of storm runoff events on real basins varying in size from 0.02 to 734 sq mi. The method is based on applying unit hydrographs to precipitations of various frequencies after deducting infiltration and retention. A concurrent study with an analytical drainage basin model provided additional understanding of the effects of some parameters. The unit hydrograph-infiltration capacity concept was selected as the most accurate practical method for predicting storm runoff. It was found that the form of the unit hydrograph could be related to drainage basin size and degree of urbanization as measured by population density. Other characteristics of the drainage basin are much less important.
