Abstract

Experiments to test relationships between slope length, percolation, and runoff were carried out in a laboratory flume under simulated rainfall at intensities from 24.2-26 mm/h. A composite soil subject to sealing was mixed from a clay and a sand and tested on 2.39 m, 7.18 m, and 17 m slopes for a minimum of 200 min. Runoff discharge is not a simple function of rainfall excess and slope length but shows a complex pattern dominated by surface sealing, rill development and headcut incision. Headcut and rill incision shows a cyclic pattern intersped with broad areas of sheetwash and colluvial deposition where percolation rates are very low
