[3] The coast is exposed to erosion by rivers and winds as well as the sea, so that a combination of denudational processes will work against a seawall. Seawalls are normally very massive structures because they are designed to resist the full force of waves and storm surge. For example, Omaha Beach seawall in New Zealand was designed to prevent erosion from everyday waves only, and when a storm in 1976 carved out ten meters behind the existing seawall, the whole structure was destroyed. If theres enough erosion on the coastline, structures that are by the water are in danger and subject to collapse if enough flooding occurs. The answer is a rip rap retaining wall, also known as a rip rap seawall. Concrete is not as popular as vinyl, but it is valued in industrial uses for its strength. [35] The construction of the seawall also provided employment for relief workers during the Great Depression and seamen from HMCSDiscovery on Deadman's Island who were facing punishment detail in the 1950s (Steele, 1985). What is the purpose of the seawall? This type of seawall is inexpensive and best suited for low-impact areas. But the riprap itself is not what prevents erosion.
