Mound type seawalls, using revetments or riprap, are used in less demanding settings where lower energy erosional processes operate. The least exposed sites involve the lowest-cost bulkheads and revetments of sand bags or geotextiles. These serve to armour the shore and minimise erosion and may be either watertight or porous, which allows water ...
This example of multiple structures includes a massive seawall and riprap revetment. A bulkhead is a retaining wall, such as a bulkhead within a ship or a watershed retaining wall. It may also be used in mines to contain flooding. Coastal bulkheads are most often referred to as seawalls, bulkheading, or riprap revetments.
Reasons can include: seawalls locking up sand dunes, coastal structures like ports and harbors that prevent longshore transport, and dams and other river management structures. Continuous, long-term renourishment efforts, especially in cuspate-cape coastlines, can play a role in longshore transport inhibition and downdrift erosion. [ 10 ]
A honeycomb sea wall (also known as a "Seabee") is a coastal defense structure that protects against strong waves and tides. It is constructed as a sloped wall of ceramic or concrete blocks with hexagonal holes on the slope, which makes it look like a honeycomb, hence the name of the unit.
They are typically about 3–5 metres (10–16 ft) high. Older-style vertical seawalls reflected all the energy of the waves back out to sea, and for this purpose were often given recurved crest walls which increased local turbulence, and thus increased entrainment of sand and sediment. During storms, sea walls help longshore drift.

You stop dead in your tracks. Your heart races, heat rushes to your face, and your mouth goes dry. Is it…? You inch closer, barely trusting what you’re seeing. Yes. Yes, it is. You’ve just ...
A tetrapod is a form of wave-dissipating concrete block used to prevent erosion caused by weather and longshore drift, primarily to enforce coastal structures such as seawalls and breakwaters. Tetrapods are made of concrete , and use a tetrahedral shape to dissipate the force of incoming waves by allowing water to flow around rather than ...
