Abstract

The dynamics of the formation of ravines (gullies) by taking the wave motion of flow into account. The article considers the question of impact of the wave motion of flow on the erosion intensity in the ravines. The technique to predict the occurrence of waves on a free surface of alluvium-carrying flows is proposed. Wave motion stimulates the intensity of the soil and ground washout. The influence of wave formation on the process of the erosion intensity is assessed by using the correction factor for the average flow velocity in the clear section.
