At the stage of the life cycle, ensuring the operational reliability and safety of pressure head hydraulic structures is an urgent task. One of the serious threats at the present stage is the destruction of hydraulic structures by the impact of non-stationary loads, by directed explosions in the immediate vicinity of the structures or on their surface. Shock waves pose a serious threat to hydraulic structures. Impulse short-term impact on the solid surfaces of hydraulic structures or on the aquatic environment characterizes the specifi cs of the problem under consideration, as the nonstationary of the process of motion of continuous media into which, in a short time interval, a volume of energy can be released that can deform or completely destroy them. Scenarios of this kind can occur either in the immediate vicinity of a hydraulic structure or as a result of the collision of solid bodies on its surface. Water upstream of the hydro technical structure and its body is a complex liquid because many of its characteristics differ significantly in size from similar characteristics of other liquids or have so-called anomalies on pressure and temperature dependences.
