Abstract

The article considers a numerical study of the movement of a water stream in the channel of the Amu Bukhara Machine Channel (ABMK). Water intake to the inlet canal is carried out from the Amu Darya river in a damless manner, therefore, ensuring the flow of clarified water into the anterior chambers of pumping stations is an urgent task. According to the developed model, consisting of hydrodynamic equations based on the laws of conservation of momentum and mass, data on the dynamics of velocities in the channel of the supply channel ABMK are obtained and zones of uneven flow in the channel are determined. Recommendations have been developed that allow the establishment of quasi-uniform motion, which helps to prevent deformation of the channel of the supply channel and reduces the flow of suspended and bottom sediments into the fore-chambers of the pumping station.
