Definition
A massive barrier or embankment constructed along a coastline to prevent erosion and protect inland areas from waves, storm surge, and flooding. Seawalls are engineered structures made from concrete, steel, or stone designed to withstand repeated wave impact and harsh marine conditions.
Example Usage
After the hurricane threatened the town, the city reinforced the seawall to protect the waterfront properties.
Origin
Compound of 'sea' and 'wall,' a straightforward descriptive term for a wall built against the sea.
Fun Fact
Some of the most ambitious seawall projects, like the Thames Barrier in London, incorporate movable gates that can be raised during storm surge to protect millions of people.
