Additional Tests on the Effect of Rainfall Intensity on Storm Flow and Peak Flow From Wild‐Land Basins

Further evidence that hourly rainfall intensity has no appreciable effect on storm flows, and only a small effect on peak flows, was adduced from statistical analysis of 4094 storm events on 15 drainage basins ranging from 13 to 760 ha in area. The basins range from humid to semiarid climates and from flat to steep topography and contain various covers (forest, brush, grass, and swamp). The marginal coefficient of determination accounted for by maximum hourly rain intensity averaged about 1% for storm flows and about 10% for peak flows. The dependence of storm flows on rain intensity did not increase in larger storms or on more responsive basins, but rather the opposite. Similar analyses so far published by others show similar effects.
