"Overtopping protection for embankment dams utilizing conventional or mass concrete relies on a continuous layer of concrete to serve as the flow surface for overtopping flows. This normally consists of a smooth, continuously-reinforced concrete slab (CRCS) constructed over a filtered drainage layer. The concrete slab and drainage layer protects the underlying embankment from high velocity flows discharging along the downstream face of the dam. Training walls are normally required at the sides of the overtopping protection to contain the overtopping flows and to protect the abutments. If the abutments consist of competent nonerodible rock, it may be possible to forego the training walls, as long as the groins are protected and the underlying embankment does not become subjected to high velocity flow."
