Soft Engineering Pros And Cons

928 Words4 Pages

Soft Engineering Soft engineering techniques deploy the use of more natural measures utilising sustainable ecological principles to improve the resistance of coastland areas to erosion and flooding. This is achieved through utilising vegetation (mangroves) and other natural systems like dunes and beaches which absorb and eventually adapt to becoming more accommodative of the impacts felt via wave action, resulting in little or no destruction (or more stable conditions) at the land- water interface/boundary (Geography LWC, 2015). Some advantages (pros) of soft engineering coastal management practices are that they are generally less expensive as opposed to hard engineering measures; they’re more attractive since they blend in with the natural environment; and they provide more long term-sustainable solutions without disrupting natural processes and ecosystems. Its disadvantages/ cons however is that there is a lower likelihood of resistance to severe storms with the exception of some soft engineering techniques like the planting of mangroves; there is need for frequent monitoring and maintenance in some cases; it may be a time consuming process before these natural systems can effectively provide optimum resistance (for instance-the time taken for afforestation or for the growing/ replanting of mangroves) and lastly, there is a periodic …show more content…

Beach nourishment can be a lengthy and expensive process and is usually undertaken during the summer which may cause accessibility problems to beach users during this time period since it requires the constant addition of sediments. (FSC, 2015) Pros 1. Regular beach nourishment leads to an overall better quality beach which gives rise to an increase in beach

Similar to the Choi, Naik’s article is written with complex sentences that are long and are introduced, elaborated on, and concluded. Plus, the article by Naik is written objectively and in third person, which means that the authors opinions and personal thoughts weren’t given; the information given is unbiased despite the fact it is favored for artificial reefs, but the article mentions the opposing side. Even though “From Balls of Concrete To Habitats for Sea Life” is for artificial reefs and believes they are helping the environment, there is no biased information or opinions given. Unlike Choi and Naik’s article, “The Disadvantages of Artificial Coral Reefs” has an informal tone due to the simple sentences that have watered down ideas that don’t expand on their ideas. However, this article was written in third person, like the other two articles.

Most water ecosystems exist where tidal flood does not take place. Tidal fluctuation results in the reduction of antagonism, due to irregular wetting and drying (Morphological and Physiological Adaptations, 2015). Mangroves distribute 18% of Australian’s coast line. They can be found in all the Australian states, except for Tasmania.

It is a product conducted at the U.S. Army Engineer Research and Development Center by the Coastal Inlets Research Program (CIRP). Surface elevation, flow velocity, sediment change and morphological change can all be calculated using the CMS.3 Modeling by Legault et al. has been used to determine a sediment budget for St. Augustine’s inlet. In order to determine the budget, they created a second report that needed to model the hydrodynamics in order to predict the amount of sediment that is transported.3 CMS has the ability to reproduce observed trends in ebb-tidal delta morphodynamics and changes in volume of notable morphologic features because of tide and hindcast waves. In order to calibrate the modeling system, CMS was used to reproduce observed water levels in the Tolomato-Matanzas estuary, the inlet’s current velocities and the ebb-tidal delta’s morphological change.

However, this method also has its advantages and disadvantages. Two positives of using the sand jet are that it selectively removes bad sediment, without any harmful side effects, and it has a portable size, making it easy to move from one area of the river to another, or from one river to another. Some disadvantages of the Sand Jet are that it doesn 't get rid of the chemicals in the water, and it is manually operated, and labor intensive, as someone has to scour a riverbed with

The controlling of the river should take this idea into account if and when it’s revamped. When the plan to cement the L.A. River was completed in the mid-1900’s, the idea of reducing the risk of flood was the only thing people were thinking about. While the risk of floods are reduced, the surrounding habitats are also reduced in size and quality. The introduction of unnatural physical barriers such as concrete prevent the river’s habitat growing and diversifying (“Los Angeles River”). Plant and wildlife have very little chance to survive in such a disconnected habitat.

In Caribbean, 36 percent coral reefs are located within 2 km of the inhabited land thus this area of coral reefs ecology have highly susceptible to pressures arising from coastal populations. The extensive construction and development for roads, housing, ports and other development has been required to support both of the residential and tourist populations. The coastal development was poorly managed therefore put stress on coral reefs through direct damage from dredging, land reclamation and sand and limestone mining for construction as well as through less direct pressures such as runoff from construction sites and removal of coastal habitat. Besides that, the loss of mangrove and sea grass which filter sediment and nutrients coming from the land has been widespread in the Caribbean which lead to add the pressure towards coral reef ecology. Next, the increased sediment in the coastal waters reduces the amount of light reaching the coral and hinders the ability of their symbiotic algae which is zooxanthellae for photosynthesis.

Off shore dredging of sand and shingle in adjacent areas increases erosion in other areas and significantly affects the ecosystem in the dredging area. Large storms easily degrade beach replenishment inputs, thus increasing costs. £20.000 per cubic meter Managed retreat In areas where Managed retreat is permitted, it retains the natural balance of the coastal system. The eroded material promotes the development of beaches and salt marshes in specified areas.

The Cold War was a conflict which arose after World War II between the United States and the Soviet Union, former allies. This war was not a traditional physical war, it was more a war of political, military and technological victory. With the use of propaganda, both would flaunt their scientific, technological achievements. It was, in essence, a battle of superiority. This war began in the mid 20th century and would end with the collapse of the Soviet Union, in 1991.

Moving towards the washrooms, one could not fail to notice a parking lot so small and crowded with the few people present at the beach. The concession stand has old bathrooms that look like they need renovation sooner than later. Walking in the beach, minds free of the worldly worries and legs free from the enclosure of the shoes, life could never get better than that. Nobody should come and take away the peace of mind that the sea breeze gives to its visitors by being rude to them or failing to perform their duty.
