Rainfall intensity influences both the rate and the volume of runoff. An intense storm exceeds the infiltration rate of the soil by a greater margin than does a gentle rain; thus, the total volume of runoff is greater for the intense storm even though total precipitation for the two rains is the same.
Witryna13 sty 2024 · Factors affecting runoff. It is generally recognized that runoff from a given watershed is influenced by two major groups of factors categorized as climatic and physiographic.

One factor is deforestation and strip mining. In these cases the surface vegetation is removed and destroys a barrier against surface pooling of water. Precipitation in these areas is likely to collect and move faster, often stripping large amounts of soil as it flows.
