This paper presents field observations of the riprap slope of a dam regarding the slope damage due to adherence of the ice floe to the slope protection when the water level fluctuates. Analysis of field observation data has made it possible to identify the nature of the slope failure, including the scope of failure, as well as the steepness of a slope resistant to ice impact. To repair the slope of the toe rock, which is pervious fill, and the drainage of the dam, a rational solution has been proposed which, on the one hand, does not lead to a rise of the phreatic surface in the body of the dam, and on the other, its entire mass resists fluctuations of the ice floe. The design concept of the slope protection can be used for both rivers and marine structures, because the geometry of the concrete beams that are the basis of the proposed solution can be modified easily, thus adapting them to specific conditions associated with both ice impacts and the geometry of the slopes to be protected.
