Breakwater is another measure of coastal protection. Breakwaters are strutures, which usually made of granite, built parallel to the coast but off shore.

Breakwater creates a zone of shallow water between itself and the coast, so that waves will break against it before reaching the coast. Thus as the waves reach the coast line, the waves energy will be largly reduced by the breakwaters thereby protect the coast from erosion. Thus it is an effective measuere of coastal protection.

  In the other hand, breakwaters are expensive to build, the cost of each breakwater is estimated to be around S$1 million, hence some less developed countries may be unable to afford it. Secondly, breakwaters are unable to provide complete protection due to the gaps between it and the coast. Thus erosion may still occur.
