REVETMENTS
A revetment is a heavy facing (armor) on a slope to protect it and the adjacent upland against wave
scour (Figure 20). Revetments depend on the soil beneath them for support and should, therefore, be
built only on stable shores or bank slopes. Slopes steeper than I on 1.5 (1 vertical on 1.5 horizontal) are
unsuitable for revetments unless flattened. Fill material, when required to achieve a uniform slope, must
be properly compacted.
