The preservation of the hydrotechnical structures from the vibration phenomenon is due to the Reserve work, which is carried out taking into account the circumstances associated with an increase or decrease in the flow in the project, an increase in the flood arrival time, a complete cessation of the water discharge pipeline, these works are completely received from the vibration phenomenon.

In the article, the work of calculating the amount of silt and sand particles in the forebay and water intake department of the PK-1512+01 KFK and SShK1 irrigation pumping station located in the large Fergana canal was carried out. By calculating the amount of turbid sediments, there are details on how to evenly distribute the flow in the forebay, how to prevent cavitation processes in the suction pipes of the pump, and how to increase the efficiency of the pump station operation mode.

At the moment, there are no clearly defined principles of cavitation types. We use an agreed-upon, widely used term in our literature. First of all, cavitation is divided into separate sections according to the reasons for its occurrence. Proceeding from this, cavitation can be divided into hydrodynamic and acoustic types. Movement of liquids and acoustics (impact of sounds) occupy a very important place in the adoption of engineering solutions. In the first case, the pressure drop passes through the critical point, changing the direction and shape of motion relative to the velocity vector. In the second case, the formation of cavitation is caused by the oscillating effects on the liquid, which can be imagined by an example of the work of hydroacoustic stations. The appearance and development of porosity in the liquid can be carried out by directing (blowing) gas to it.Therefore, natural cavitation and Artificial, a solid body that is formed under external influence, that is, interacting with a liquid; as well as artificial, cavitations that occur under the influence of gas, which are forcibly directed to certain points of the flow, are known.
