The hydrology of small impervious areas

Open publisher page 29 citations

Abstract

The rainfall‐runoff relationships on several impervious urban drainage areas varying in size from about 0.4 to 1.0 acre were investigated. The effective storm pattern, divided into a sequence of 1‐minute inputs, provided the basis for generation of a corresponding sequence of runoff outputs, which were combined to produce the total runoff hydrograph. The basic output is a unit hydrograph resulting from an effective rainfall input of 1 minute's duration. (Key words: Runoff; unit hydrographs; urban areas)
