base material that supports the riprap revetment. The primary feature of a slump failure is the localized displacement of base material along a slip surface, which is usually caused by excess pore pressure that reduces friction along a fault line in the base material. Figure 1-4 illustrates a slump failure. Probable causes of slump failure are:

Seawalls and revetments - Coastal Wiki

A revetment is, just as a seawall, a shore parallel structure. The main difference is that it is more sloping than a seawall. A revetment has a distinct slope (e.g. 1:2 or 1:4), while a seawall is often almost vertical, the surface of a revetment might be either smooth or rough (a seawall is mostly smooth) and that the height of a revetment ...

Revetments were subdivided in (a) quarrystone revetment, when blocks of rocks were used as the dominant material, and (b) other, when any other type of material was used. Seawalls were made of (a) wood, and (b) concrete. The third group consisted in wood or concrete seawalls that had a toe protection of quarrystone revetment.

DESIGN OF SEAWALL - IJSDR

The least exposed involve the lowest cost bulkheads and revetments of sand bags or geotextiles. These serve to armour the shore and minimize erosion and may be either watertight or porous, which allows water to filter through after the wave energy has been dissipated. Figure 4 shows mound seawall.
