Question

____ is constructed to protect coastal land from sea wave and current erosion.

• A. Break Waters
• B. Masonary Sea Wall
• C. Groins
• D. Dredging

Hint:

Masonry sea walls are essential for protecting coastal infrastructure but may require maintenance to prevent structural weakening over time.

Answer 1

The Correct Option is B

Masonry sea walls are vertical or sloped structures built parallel to the shore to protect coastal areas from wave action and erosion caused by sea currents. These walls are made of durable materials such as stone, concrete, or brick to withstand harsh marine conditions. Unlike breakwaters, which are offshore structures to reduce wave energy, sea walls directly protect the coastline. They are extensively used in areas with high tidal forces or significant risk of erosion due to storms.
