To prevent coastal erosion.
In Bridlington, coastal defenses such as seawalls, rock armor, and groynes are commonly used to protect the shoreline from erosion and flooding. These structures help to absorb wave energy and reduce coastal erosion, safeguarding the coastal properties and infrastructure in the area. Additionally, beach nourishment and dune restoration projects are also implemented to enhance natural defenses against coastal hazards.

Sea defenses provide protection against coastal erosion and flooding, helping to safeguard lives and property. However, they can be expensive to build and maintain, may disrupt natural coastal processes, and can have negative impacts on the local ecosystem and habitats. Proper planning and design are essential to maximize the benefits of sea defenses while minimizing the drawbacks.
there has been a sea wall built out to sea, but this has increased erosion ferther down the coast.
The sea defenses at Mappleton in the UK were built in 1991 as a response to coastal erosion threatening the village and its farmland. The defenses consist of rock groynes and a mass concrete seawall to protect the coastline from erosion by the North Sea.
Hastings features several coastal defenses to protect against erosion and flooding. Key structures include sea walls, groynes, and rock armor, which help to dissipate wave energy and manage sediment movement. Additionally, the town has implemented beach replenishment projects to maintain sand levels and strengthen the shoreline. These measures collectively aim to safeguard the coastal area and its infrastructure from the impacts of the sea.
The two most expensive coastal protection methods are the sea wall and the offshore breakwater methods. By Tahmina Hussain, GCSE Geography Student. SJT
The coastal defenses that hold beach sediments in place are called "groynes." These structures extend from the shore into the water and are designed to interrupt the flow of water and sediment along the coastline, helping to prevent beach erosion. By trapping sand and sediment, groynes can help maintain and build up beach areas.
1 is a groyne which absorbs some wave power and catches sediment. another is a sea wall which deflects wave force and pushes it out to sea. i dunno any others I'm trying to find that out my self at the moment! lol
Coastal batteries positioned around San Francisco Bay and others.
sure I'm not going to answer that completely but i think yes and no yes cause they sound important no cause i don't know what they are.
