Coastal hazards are natural and manmade events that impact the boundary between the ocean and the shoreline.
Risks from coastal hazards are expected to increase in the future as development and populations continue to grow in coastal areas and a rise in sea level occurs due to climate change.
Storm surge results from the combination of low pressure associated with an oncoming storm and high winds which push on the ocean's surface causing a temporary rise in the level of the sea.
Damage from storm surge is likely to result causing beach erosion that undermines foundations.
Coastal erosion is a natural process that consists of the breakdown of rock and sediments at the shoreline, both above and below the water surface.
