ABSTRACT:
A method and related revetment system for preventing shoreline slope erosion due to wave and hydrostatic forces. The revetment system includes an elongate, grid-like frame structure of predetermined shape which is set into an excavation in the slope of substantially complementary shape. A filter fabric liner is disposed to overlie the surface of the slope excavation so as to line the excavation beneath the frame structure. The filter fabric liner is sufficiently porous to allow water to pass therethrough while preventing the movement of the soil material of the slope therethrough. The method further includes setting the frame structure into the slope excavation and over the filter fabric liner such that an upper surface portion of the frame structure is substantially continuous with the natural contour of the slope. The volume defined by the frame structure is filled with an aggregate material of a size such that water may move relatively freely therethrough to in effect provide a porous wall structure which can withstand the wave forces. The filter fabric liner and the aggregate material wall structure also serve to substantially prevent the buildup of hydrostatic pressure therebehind by allowing the flow of water therethrough, while preventing the soil material of the slope from washing therethrough.
