Hard engineering
Hard engineering options tend to be expensive, short-term options. They may also have a high impact on the landscape or environment and be unsustainable.
5 of 12
Soft Engineering
Soft engineering options are often less expensive than hard engineering options. They are usually more long-term and sustainable, with less impact on the environment.
6 of 12
Shoreline Management plan
A large-scale assessment of the risks associated with coastal processes which seeks to reduce these risks to people and the developed, historic and natural environments.

New defences are built further out in the sea in an attempt to reduce the stress on current defences and possibly extend the coastline slightly.

Curved seawall
help in breaking the waves and lessen the wave energy.
11 of 12
Mound Seawall
involve the construction of mound type structures in situations where wave energy is low and less demanding settings which are least exposed use a facing of sandbags, stones or porous rocks that form concrete armor for the embankment.
