More about coastal inundation

Coastal inundation can be a threat to the safety of inhabitants of low-lying coastal areas. Coastal inundation is the flooding of coastal lands by raised ocean waters. It can be made worse by flooding in adjacent lowland rivers. Most coastal inundation problems have arisen from coastal development located in low-lying coastal areas, or areas located too close to the shoreline.

Coastal inundation can cause substantial damage to public and private property, including the contents of buildings. It can cause a breakdown of transport and communications.
