Abstract
The main definition of long waves is given in the article. The basic hydrodynamic equations of nonstationary flows-Saint-Venant based on the laws of conservation of mass and momentum. The conditions of application and the main hypotheses adopted to the planned hydrodynamic equations of the water flow movement in the section of the river bed located in the zone of influence of hydraulic structures on the flow dynamics are analyzed in detail. It is substantiated that in solving many applied hydrodynamic problems, including when calculating the motion of long waves in river channels, difficulties are encountered with the adoption of boundary conditions. In addition, in the zones of influence of hydrotechnical or hydropower facilities, the dynamics of the flow of modeling of the entire channel is impossible, it is necessary to isolate the calculated fragment and assign boundary conditions from general considerations. With an increase in the size of the calculated fragment, the planned picture is adjusted under the influence of the channel shape and friction on the bottom, which increases the reliability of the results in the researcher of interest to the region.
