Coastal hazards are physical phenomena that expose a coastal area to the risk of property damage, loss of life, and environmental degradation.Rapid-onset hazards last a few minutes to several days and encompass significant cyclones accompanied by high-speed winds, waves, and surges or tsunamis created by submarine (undersea) earthquakes and landslides.
Coastal erosion is one of the most significant hazards associated with the coast. Not in terms of a rare massive release of energy or material resulting in loss of life, as is associated with tsunami and cyclones, but in terms of a continual chronic release that forms a threat to infrastructure, capital assets and property.
Coastal flooding during Hurricane Lili in 2002 on Louisiana Highway 1 (United States). Coastal flooding occurs when dry and low-lying land is submerged by seawater. [1] The range of a coastal flooding is a result of the elevation of floodwater that penetrates the inland which is controlled by the topography of the coastal land exposed to flooding.

Coastal/lakeshore hazards – Hydrological hazards that may affect property, marine or leisure activities in areas near ocean and lake waters including high surf and coastal or lakeshore flooding, as well as rip currents.
This management program is a voluntary partnership between the federal government and US coastal and Great Lake States. The state of New Jersey developed this program to manage, protect, and develop its coastal lands and waters. New Jersey develops a comprehensive five-year strategy to address the high priority needs of the Coastal Management ...
Coastal and estuarine ecosystems act as buffer zones against natural hazards and environmental disturbances, such as floods, cyclones, tidal surges and storms. The role they play is to "[absorb] a portion of the impact and thus [lessen] its effect on the land". [ 22 ]
Coastal erosion may be caused by hydraulic action, abrasion, impact and corrosion by wind and water, and other forces, natural or unnatural. [3] On non-rocky coasts, coastal erosion results in rock formations in areas where the coastline contains rock layers or fracture zones with varying resistance to erosion.
