Abstract Purpose. The estimation of the main parameters of breakthrough wave flowing over the crest of supporting construction of hydro technical unit.
Methods. The main provisions of the evaluation are based on the method of I.I. Agroskin. The movement of the stream flowing over the crest of the supporting structure is considered as a form of sharply changing uneven fluid motion, called hydraulic jumping.
Findings. The compressed and first conjugate depths are determined, and a direct relationship is obtained to determine the second conjugate depth, assumed equal to the maximum wave height behind the supporting structure.
Application field of research. The method of sequential calculation of parameters and plotting the flow of the generated dislocation wave (displacement wave) will make it possible to assess the possible consequences of flooding and the preparation of initial data for planning measures to protect the population and objects.
Conclusions. The obtained research results can be used in the design of hydraulic structures, taking into account the possibility of the generation of displacement waves.
Keywords displacement wave, compressed depth, second conjugate depth, wave motion plot
