Abstract

Hortonian runoff was measured in the laboratory from uniform slopes of lengths of 1.5, 3.0, and 6.0 m for steady, high-intensity rainstorms with durations of 1.0 to 7.5 min. A clear reduction in runoff per unit slope length was found as slope lengths were increased. The runoff data were used to validate a simple process-based model that combines the Philip-two-term infiltration equation with the kinematic wave overland flow principle. The predicted and experimental results agreed well. Laboratory findings were extrapolated with the aid of the model to slopes and rainfall durations similar to those found under West African conditions
