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 . [ 1 ]
The Galveston Seawall is a seawall in Galveston, Texas, that was built after the Galveston hurricane of 1900 for protection from future hurricanes. Construction began in September 1902, and the initial segment was completed on July 29, 1904. From 1904 to 1963, the seawall was extended from 3.3 miles (5.3 km) to over 10 miles (16 km). [2]

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 ...
The reconstruction of the seawall, including new construction of 3,188 ft (972 m) [1] in gaps where it had not previously existed [2] [3] began in 2017 and will be completed in 2018. [4] The storm precipitated reconsideration of seawalls and other methods of coastal protection to mitigate storm surges and sea level rise along the coast.
Cunningham continued supervising construction into his last days despite being ill and, on at least one occasion, went to check the seawall's progress still wearing pajamas. He died on 29 September 1963, long before the wall was finished, but remains the one most associated with the project, and a commemorative plaque can be found near Siwash ...
