Abstract |
The purpose was to obtain equations which predict the 30-minute unit hydrograph for small urban watersheds. Equations were derived for models of the product form that correlate basin topographical features with hydrographic parameters. The models were transformed by natural logarithms so that linear regression methods could be used to obtain estimates of the exponents in the equations. The equations were applied to a wide variety of watersheds to demonstrate their validity. Confidence intervals were derived for the estimation of each hydrographic parameter. Nomograms were supplied to provide fast and accurate solutions for each equation. |
