Abstract
The features of the transformation of the profi le of the slope of fl oodplain dams and banks of water bodies with a change in the depth and parameters of the wave action, including the place where the destruction of gravel slopes begins, are considered. The results of modeling studies on slopes with a laying equal to 5 are presented, according to the results of which the infl uence of a change in the relative height of the wave crest within 0.01…0.10 on the type of the reshaped slope profi le is revealed. The results of comparison of the obtained experimental data with Van-Human data for profi les of two main types: erosional and alluvial are analyzed. Recommendations are given for determining the stable laying of a slope in the coastal wave zone of a reservoir or a large watercourse with different fl atness of creative waves. It has been established that the fl atness of the waves does not have a signifi cant effect on the magnitude of the stable initiation of the slope with a known average size of the unbound material that composes it. With an increase in the ratio of the height of the oncoming wave to the average diameter of the material forming the slope, the stable laying in the coastal wave zone increases and its value reaches 10.
