( Built parallel to coast ) |
Breakwaters are usually made of granite. They are often used to protect a harbour or a stretch of coastline. They can be built with one end attached to the coast or away from the coast, parallel to it. When constructed offshore, it create a zone of calm water between itself and the coast, and allow deposition to occur, forming beaches.
- Effectiveness
- Long term protection ( lasts up to 15 years )
- Break the force of high-energy waves ( destructive waves ) before they reach the shore.
- Expensive to construct ( Estimated cost : S$1 Million per breakwater )
- Unable to provide complete protection, hence erosion may still occur.
