Breakwater protection from waves

Pictures of Breakwater 

All in all of Breakwater 

In conclusion, breakwater can protect the coast but it can provide full protection. It is also too expensive for some less developed country.

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 .

How is Breakwater Effectiveness ?? 

-Fixed breakwater- 

Fixed breakwaters usually consist of mounded rubble or concrete barriers. These types of breakwaters offer protection from high and fast-moving waves and can still offer protection even if mildly damaged in heavy storms. Stone or rubble that is dislocated by heavy waves can be easily repaired without having to replace the entire structure. Some aquatic creatures use breakwaters as a habitat, and fixed breakwaters that are placed with open segments allow free movement of aquatic wildlife.

-Floating Breakwater- 

Floating breakwaters are moored, box-like or pontoon-like structures placed out from the shoreline to break up wave intensity. Floating breakwaters are effective in wave heights of less than 6.5 feet. They are appropriate for use in areas where poor soil conditions make a fixed breakwater unfeasible and are less expensive to install than fixed breakwaters.Floating breakwaters do not interfere with water flow, fish migration or the movement of sediment and can be easily moved or rearranged. Floating breakwaters are also often more aesthetically pleasing than fixed breakwaters.

-Summary of Effectiveness-

In conclusion, both breakwaters can last 15-30 years and creates a zone of shallow water between itself and the coast,waves will break against the breakwater before reaching the coast.
