Storm Runoff as Related to Urbanization in the Portland, Oregon-Vancouver, Washington Area

From abstract: "A series of equations was developed to provide a better method of determining flood frequencies in the Portland-Vancouver urban area that is now available. The resulting regression equations can be used to compute peak discharge and storm runoff with a standard error of estimate of approximately thirty percent." This report contains captioned, black-and-white photographs and a colored map.

Storm Runoff as Related to Urbanization Based on Data Collected in Salem and Portland, and Generalized for the Willamette Valley, Oregon

Abstract: Storm runoff as related to urbanization is defined by a series of regression equations for Salem and for the Willamette Valley, Oregon. In addition to data from 17 basins monitored in the Salem area, data from 24 basins gaged in a previous study in Portland, Oregon-Vancouver, Washington were used defining the Willamette Valley equations. Basins used to define equations ranged in size from 0.2 to 26 square mi. Rainfall intensity varied from 1.8 to 2.2 in. for the 6-hour, 0.020 exceedan… more
