Problem-to scour the sea-coast. One of the main causes of coastal erosion problems are: Global warming could be a factor reinforcing the severity the coastal erosion problem due to the effects that cause global climate variability and sea level rise it resulted in storms and waves that blow toward the coastline. With frequency and severity increasing and changing direction, until the serious erosion occurred until the loss of the space coast and caused land subsidence along the coast increased. Make the housing community. Causes of coastal erosionOccur for many reasons can be divided into 2 main causes is caused by natural processes and human activities.1.0) is caused by natural processes.-Typhoon and storm will cause winds into coastal clash. Make a mass of sand is blown out from the coastal areas over a period of time and be blown sand mass back in again one at a time, which may cause the sand mass, are borne away from the coast and the sand mass that was borne into the balance.-Water-water Affect the movement of soil and sediment along the shoreline sand mass, which may also cause imbalances, such as occurs with the Typhoon and storm, it will contribute to coastal erosion.2.0) resulting from human activities.1. the development of coastal area economic development makes available various construction in coastal areas is a lot like creating an industrial estate. Creating transport routes. The construction of a deep-sea port, which may result in changes to the geological condition of coastal resources and ecosystems in the area, lack of balance and lead to coastal erosion are easy.2. space invasion mangrove aquaculture as a source of development, such as the black tiger shrimp. Cause a loss of resources which are important in the prevention of the wind. Wave flow again all the roots of the mangrove wood also helps trap the sediment mud sediment dispersion, as well as help cling together often makes it difficult to collapse too. So in a mangrove area intrusion. Can coastal erosion problems easily?3. the creation of dams and reservoirs upstream areas causes the water flow caused the slowdown. So a certain amount of sedimentation sludge is in the trunk and some is quarantined the area above the dam. Make the flow of sediment accumulated at the mouth of the River, there is less. There is therefore a lack of sediment is added to replace takonboriwen coast that was borne out to. As a result, the coastal area due to coastal erosion are easy.4. groundwater pumping. Contribute to cause subsidence of the soil with the section cause shoreline erosion.5. global climate change due to rising sea levels. Make sea water pushes more and more land. Result in the coastal coastal erosion occurred.
