Development Of Marina Barrage Around Marina Bay Environmental Sciences Essay
Environmental Impact and Assessment (EIA) is the evaluation of the conceivable impacts on the surroundings caused by a proposed project. We will discuss how the construction and operation of the Marina Barrage and expansion around Marina Bay can lead to destruction of reef and coral growth.
The construction and operation of marine Barrage and production will affect the normal water quality of the marine bay. The reason being these developments and engineering will result in decreased flow of water post secondary institution meaning into the sea. This might also lead to change in downstream water quality and circumstances. The salinity of the water body may be altered by these advancements and integral of secx constructions. Reduced water flow may lead to decreased nutrients in the sea and developed of silt which might result in the long-term disturbance of the ecosystem. Eutrophication is also likely to result therefore destruction of coral and reef progress (2).
The progress of algae on top of the corals may wrap up killing them since sunshine is blocked which is necessary for the procedure of photosynthesis. Since this Marina Barrage can be designed for tourist activities, it may conclude with destruction of corals for tourism uses. Waste dumping is also likely to increase and in addition increased of essential oil spills and other products during the construction. This may wrap up contaminating the water leading to the death of corals. Oxygen amounts will probably decrease resulting to loss of life of coral reefs. Dredging and dynamiting method in this task may wrap up in the removal of components from the living reef.
According to CortÃ©s (2003), the development may lead to increased population which may result in increased pressure on the water resources. Extra corals will tend to be removed for purposes of souvenir, rings and other uses. Turbidity can be likely to increase because of particles floating on drinking water. This helps prevent light from penetrating the normal water and therefore the corals suffer. Corals generally flourish in clean and pure water.
Construction can also lead to soil erosion. This outcomes in more particles finding yourself in the water body which addresses the corals. This â€˜smoothersâ€™ the corals and lead to their death. This is consequently of destruction of mangrove and different tree species which act as filters of sediments. In this instance a lot of vegetation may be destroyed in constructing and growing marine barrage.
The corals are incredibly important since they are a source of tourism and also help in controlling water currents, strong waves and storms. Reefs will be also resources of medicine and are being used in treatment of a variety of diseases such as for example leukemia, heart disease and also deal with ulcers. The corals as well use carbon dioxide to form their shells and therefore in a way prevent and minimizes pollution (3).
During the creation of marina bay, sediment plume monitoring of the dredging and reclamation gets results are done constantly because they are considered the very best priority. Should a direct effect on coral reefs get anticipated, mitigation measures must be put in location to reduce or removed the effect. The sediment plume are monitored using a mixture of desktop and discipline equipment with the calculations of the daily spill in conjunction with the concentrations of the total suspended solids recorded by online optical sensors, secchi depth monitoring and water quality surveys. Water top quality surveys to check the caliber of water are as well done continuously on a periodic basis to record the water quality circumstances around the development web page. Optical sensors were deployed on the seabed at different locations to monitor water quality. Turbidity, temperature, PH and dissolved oxygen levels happen to be monitored by a combination of sensors to be able to enable preventive procedures to come to be undertaken. One problem faced is usually that the turbidity sensors at the site cannot differentiate between the loadings created from dredging and reclamation activities, and pure variability in background conditions.
Lastly translocation methods were also regarded as and the corals situated directly below the expansion site were relocated to some other pre-selected location. Separate study must first be carried out to define the right relocation site for this. One good thing about this mitigation measure can be that translocated corals usually have high survival amount of approximate 90%. Divers mixed up in relocation of corals must be properly trained in order not to ruin the corals. Divers in some cases face difficulty because of poor visibility caused by silt suspended in the water. Visibility may be so very bad that divers may need to bump into coral to notice them. This will reduce the number of coral reef succumbing to death.
New mitigation measures that could be implemented include the creation of artificial reefs to provide compensatory mitigation for impacts to hardbotton habitat from construction activities. The selection of supplies for artificial reef structure is important. The make use of hard and tender corals, sponges differ and factors including the depth of water in which reefs to be built and the option of crevice space for shelter must be considered.
Another measure is the utilization of surveying techniques in the design and siting of costal development projects to avoid and reduce adverse environmental impacts. Modern times have seen the advancements in high-classification surveying technology and 3-D laser beam scanning technology which helps in increased confidence in survey info, reduced need to return to site to double check or acquire additional data, faster delivery of finished survey, the richness and top quality of the study is improved (4). One of these is the Laser beam Airborne Depth Sounder (LADS) that is useful in identifying the seafloor topography and position of hardbottom areas that allows for improvements in design and style, siting and affect minimization. On the other hand this technology remains high priced compared to ground survey techniques.
In conclusion, the development and development of Marina Barrage around Marina Bay in Singapore is likely to result to destruction of coral reef. This may bring about death and decreased amounts of the coral reef. The impacts can include change in water top quality, eutrophication, and reduced movement of water which in ways will affect the development of coral reefs.
