It is built parallel to the shore at the transition between the beach and the mainland or dune, to protect the inland area against wave action and prevent coastal erosion. Seawalls can be combined with jetties in port areas, to stabilise the sides of navigation channels and tidal inlets and to avoid siltation. Seawalls are usually massive structures designed to resist storm surges. The height of a seawall will at least cover the difference between the beach level and the mainland, though commonly seawalls are built higher to protect the land against wave overtopping. Seawalls are also used to stabilize eroding cliffs and protect coastal roads and settlements. The shape of the seawall face determines its capacity to reflect or to dissipate wave energy. Smooth, vertical sea walls mainly reflect wave energy seawards. They possibly create turbulence and suspending sediments, thus further increasing the risk of erosion. Vertical seawalls can also cause a scour hole at the foot of the structure leading to its instability. Slopes and irregular surface of the structure design of seawalls can improve their performance, allowing wave breaking, energy dissipation and scattering of the direction of wave reflection. Seawalls are often found in the case of narrow or steep beaches, where a typical breakwater is either too large or not economical.

Seawall definition

A seawall is a form of coastal shielding that provides protection to any structures and settlements close to the coast from sea action and processes such as tides and tsunamis. Instead of the coast being exposed, the seawall will be exposed to all sorts of coastal processes such as erosion. Despite providing protection, a seawall conflicts with the active nature of the sea and comes between the interaction between land and sea.
