Quantitative sheet wash estimation on the basis of surplus debris concentration at the surface

Abstract

A new technique is developed in order to obtain quantitative estimation of sheet wash value in arid regions using debris surplus at the surface. Two modifications of the technique are elaborated both for horizontal surfaces and for slopes of various steepness. The technique permits to estimate the denudation values for large time intervals (such as the duration of the surface existence). The technique can also be used for detailed studies of the slope transport mechanism of various fractions of debris.
