The main objective of the hydraulic design is the selection of the position of water intake cross section at the curved parts of the watercourses which excludes the sedimentation of front end wall. This problem is impeded by the nascency of transverse circulation at a curved part which leads to the changes in kinematic structure and capacity of a flow. The necessary data for water intake cross section selection in the first place is the texture of the deposits, longitudinal and transverse bottom velocities. On the basis of experimental data and theoretical solutions of the flow motion at the curved parts of the watercourses the authors got the equation for determine the distance from the beginning of the curved part to the water intake cross section of the structure. The obtained formula was tested at the stream model on a scale of one to ten by the method of Froude.
