Erosion of the banks of rivers brings enormous damage to the national economy of many countries. To combat them, various regulatory structures are being built: longitudinal dams, transverse traverse dams, watertight and permeable spurs, and combined transverse dams. Many issues of their design are sufficiently developed, including in our works, and are successfully applied.
This research aims to develop a method for hydraulic flow asymmetrically constrained by through pile-type spurs. The conditions of the planned task of the ratio of the flow width to the depth of more than 6 were also observed. The degree of restriction of the flow by spurs varied from zero to one, and the installation angle of the spurs from 600 to 900. The study of the velocity field showed their similarity with the main provisions of the theory of turbulent jets. The velocity distributions in both zones of turbulent mixing are universal and obey the theoretical Schlichting- Abramovich dependence. The expansion coefficient of the jet is 0.20. Theoretical studies have obtained dependences for determining the velocity in a weakly disturbed core, occurrent flows, and the spreading regions' lengths, which determine the installation locations of subsequent spurs.
