Model for calculation of stabilized gully morphology

Abstract

For taking erosion-control measures the maximum final size of gully is important. Static model for calculating the longitudinal and transversal profiles is proposed. Gully is supposed to be stabile, formed in cohesive ground, the stream velocity - to be higher than critical one, at which accumulation of little particles begins, and at the same time to be lower than the scouring rate. In the model the whole range of water discharge is taken into account. The corresponding computer program has been compiled.
