Managing coastal environments - Essay Example

In 1950-1970s, one of the methods used to achieve protection is the establishment of hard rock protections. Although the said method is aimed to minimize the effects of coastal erosion, it caused negative effects such as the increase of the power of the energy waves that can hit the land. This can be attributed to the magnification of wave action that intensified the momentum of the waves. The accumulation of knowledge on the basis of research and data gathering, the advancement of new methods led to the continuous improvement of methods to lessen the effects of coastal erosion.

There are different strategies that can be cited that were applied and empirically observed in different localities and countries. One of the examples of methods applied is located in Townsville, North Queensland. The case of the said locality is having natural erosion in the coast in relation to the two tropical cyclones that affected the area for two consecutive years. The protections that had been established had not been enough to sustain the effects of the erosion. This had effects in the tourism of the area since the recreational beaches, which are the main source of livelihood, became seriously eroded.

For that matter, actions had been taken by the local council and the authorities to be able to restore facilities to prepare for the vacation season. Included on the proposed action plan is the establishment of new facilities for the tourists, restoration of the beach and construction of four rock headlands to slow the waves and trap sediments. Through the state legislations and redevelopment proposals, the main sources of funding are the state disaster fund and the council supplementary fund.

Another case is the Tweed River in New South Wales which is human induced erosion. Actions were taken to be able to keep the river mouth clear on the basis of the susceptibility to erosion. The training
