Erosion means the elimination of land by elements such as wind, water and ice. ("What is coastal erosion") Coastal erosion occurs when a destructive wave depletes a part of the coast. The four ways this occurs are corrosion / wear, hydraulic pressure, wear and corrosion / solution. ("Internet Geography") Corrosion / wear refers to the material being thrown through the waves at the bottom of the cliff. The hydrodynamic effect is that when the waves hit the bottom of the cliff and the air is pushed in real time air is washed away when the wave leaves and often the material bursts.
Confirmation that coastal erosion is a problem: Because the coast has short-term characteristics, it can naturally erode or absorb sediment so as to cope with changing force; therefore it is a problem that coastal erosion is a problem It is very basic to check. 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. Identify the causes of problems that need to be analyzed, consider possible causes (natural and man-made) and quantify past and present causes. The magnitude and strength of the impact may be in the future. At this stage, not only field observation and data collection but also field observation and data collection of the socioeconomic (including historically available) data of the area are necessary.
Social and environmental problems caused by coastal erosion are related and easy to observe. Loss of aquaculture (fish and shrimp pond) by erosion will lower the productivity of the fishery and increase the number of unemployed people. 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
