Reference to coastal erosion describes the view that coastal erosion is caused by a natural process caused by human intervention. For decades, the rapid coastal eroding method was to establish coastal defense, trying to delay or even stop the erosion. The first attempt was considered successful, but after several years of effort, people have realized that the power of the ocean and waves can overcome human attempts. If you have to deal with enormous costs, only protection can succeed.
There are two general definitions of coastal erosion. First, coastal erosion is often defined as the loss or loss of land along the coastline due to the effects of waves, flow, tides, wind by water, water ice, and other storms. Reclamation of the land on the coastline is given data measured in tidal tides, seasons, other short-term cycling processes. Finally, coastal erosion is also defined as a process of long-term removal of coastline sediments and rocks, leading to loss of land and retreat to coastline land. It can be caused by water, wind, shock and other natural or non-natural corrosive forces.
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. Confirming that coastal erosion is a problem is very fundamental. In the sightseeing area, in coastal erosion, the problem of the waterside town / housing and cultured farm (pond) is coming up. Any legal issues related to coastal management and development should be considered and discussed
