The Environmental Tragedy of Coastal Erosion

Environmental tragedy of coastal erosion The majority of the US population live on or near one of the coasts. Protecting the beach is a very expensive effort and there have been many discussions on how the country should discuss. On the East Coast, the current strategy is the "beach nutrition program" which collects sand from available sources and returns it to the eroded beach (Michaels, 01). In 1999, the US government spent about $ 150 million on beach nutrition programs, state and local governments, and those with their beach assets spent more on these projects (Michaels, 01).

Social and environmental problems caused by coastal erosion are related and easy to observe. The loss of aquaculture (fish and shrimp pond) by erosion will decrease the productivity of the fishery and increase the number of unemployed. Erosion affects sightseeing and urban areas with a similar effect, and declining real estate value is a major problem. The coastal protection measures are improperly designed, constructed, maintained or parked in certain places such as hotels and facilities protecting the beach, but if the adjacent coast is eroded, the problem is even more severe . (Committee 4.2). Or it may stop on the basis of ownership (high public and private value) or jurisdictional or administrative boundaries, not the boundary of the system reflecting the natural processes. These "solutions" produce more questions than answers

Understanding key processes: Understanding how coastal erosion is a problem is to understand how important processes of coastal dynamics and coastal operations are problematic is to understand the process of natural systems It is important to determine the boundary. Many mathematical / numerical and physical models of coastal systems are developed as tools to understand the behavior of coastal systems. These tools can predict interactions between the evolution of the coastline and the underlying cause of the problem and the options that may be implemented in the short term and long term. Therefore, these tools contribute to countermeasure planning and design and coastal erosion management.

Since coastal erosion may not be an issue, understanding important processes of coastal dynamics, past and present, and short- and long-term coastal development is important for managing coastal erosion problems. This can be quite complicated, and it may be controversial if there are many conflicts of interest in the coastal environment. The main basic principles of coastal erosion management are as follows (NRC, 1990; ARC, 2000). Confirm that coastal erosion is a problem: Naturally erode or absorb sediment naturally to cope with changing forces due to short-term characteristics of the coast. Confirming that coastal erosion is a problem is very fundamental. In general, coastal erosion is problematic in sightseeing areas, waterfront cities / residential areas and fish farms (prawn pond). Any legal issues related to coastal management and development should be considered and discussed
