How is Breakwater Ineffectiveness ??

-Fixed Breakwater-

Fixed breakwaters are semi-permanent structures that require construction by a knowledgeable person with an understanding of the area's wave transmission. Construction costs can be relatively high when compared to floating breakwaters. Breakwaters that are continuous can pose an ecological hazard when placed in wetlands by barring organisms from entering or leaving.. Fixed breakwaters are often an eyesore--an aesthetically displeasing sight on the shoreline

- Floating Breakwater -

Floating breakwaters are not effective in areas with high or fast-moving waves. In heavy storms, these breakwaters are subject to failure and if they come detached from their moorings they can become a danger. Floating breakwaters have the advantage of being detachable when not in use, but the labor costs to replace the breakwater can be high when compared to a fixed breakwater.

-Summary of Ineffectiveness -

In conclusion , both breakwaters are expensive to build .As each breakwater is estimated to cost around S$1 million dollars . Therefore , less developed countries may not be able to afford .
In addition , Breakwater is also unable to provide a complete protection due to gaps between one breakwater ,thus erosion for other parts of the coast may still occur .
