Conclusions
When calculating the intensity of pressure fluctuation on a revetment for the surface regime beyond a dam with a ledge by the appropriate relations [3] it is necessary to take into account that the dispersion of the turbulent component given by this calculation is commensurate with the dispersion of the wave component of presssure fluctuation, which presently can be determined from the results of hydraulic investigations. The data given in [5] can be used for estimating the intensity of the total value of pressure fluctuation on a revetment for a surface regime beyond a dam with a ledge under conditions of the two-dimensional problem and in the range of relative heights of the ledge d/hc=3–6.5 and Froude numbers in the vena contracta on the ledge Frc=8–50.
