Both Del Mar and Oceanside regularly dish out dollars to add sand to their shrinking beaches, in part, some believe, because property owners build sea walls to protect the cliff or property from waves, which means no room for the beach to grow.

A seawall is constructed at the coastline, at the foot of possible cliffs or dunes. A seawall is typically a sloping concrete structure; it can be smooth, stepped-faced or curved-faced. A seawall can also be built as a rubble-mound structure, as a block seawall, steel or wooden structure. The common characteristic is that the structure is designed to withstand severe wave action and storm surge. A rubble-mound revetment often protects the foot of such non-flexible seawalls.

A seawall or sea wall is a form of coastal defense constructed where the sea , and associated coastal processes, impact directly upon the landforms of the coast. The purpose of a seawall is to protect areas of human habitation, conservation, and leisure activities from the action of tides , waves , or tsunamis. Seawall designs factor in local climate, coastal position, wave regime determined by wave characteristics and effectors , and value morphological characteristics of landform.

Various environmental issues may arise from the construction of a seawall, including the disruption of sediment movement and transport patterns. Seawalls are constructed from various materials, most commonly reinforced concrete , boulders, steel, or gabions.

Seawalls are often found in the case of narrow or steep beaches, where a typical breakwater is either too large or not economical. Curved or stepped seawalls are designed to enable waves to break to dissipate wave energy and to repel waves back to the sea. They are frequently used in locations where further shore erosion will result in excessive damage to coastal roads and settlements, providing a high degree of protection also from flooding. Construction costs vary according to the shape of the seawall structure: the volume of the seawall depends on the required crest level, on the foundation level, the wave loading, and acceptable overtopping rates. Under storm conditions a non-breaking standing wave pattern can form, resulting in a stationary clapotic wave which moves up and down but does not travel horizontally. First Known Use.
