CALCULATION OF TOTAL CHANNEL EROSION IN COHESIVE SOILS

Abstract

This article highlights the main theoretical and practical issues of calculating general erosion processes in cohesive soil channels. The dynamics of flow saturation with particles and its dependence on flow velocity, sediment concentration, and the physical properties of the soil are studied. Integral consideration of parameters such as flow, topography, geology, and other channelforming factors is included. The separation of soil under the influence of turbulent flow and the empirical relationships of this process are described. As a result of the research, mathematical models and calculation methodologies for assessing erosion processes in cohesive soils are proposed. The calculation of the free surface curve was carried out using nomograms based on the Hydoproject methodology. Hydraulic parameters of the channel were determined, and its profile was reconstructed based on this methodology.
