Abstract
This paper presents the results of studies of the processes of intense planned deformation of the channels, which are formed as a result of erosion and collapse of the banks by the flow. The substantiation of forecasting the channel-forming activity of the flow and its management is given. A generalization is given of the methods of combating the intensive collapse of river banks, the organization and technology of construction with obtaining reliability, economic efficiency and environmental cleanliness. To carry out channel straightening work on rivers flowing in arid areas, it is possible to use the design of a cut, which should have the smallest approach angle of the dynamic axis of the main flow, the greatest drop in the marks of the beginning and end of the cut, its short and straight route and the minimum amount of excavation. When assessing the effect of planned deformation on the stability of the channel, a formula is presented for calculating the depth of erosion, dimensionless criteria that determine the possibility of formation of erosion for various situations, which made it possible to select the types and designs of bank protection structures.
