Ban Khun Smuth Chin is the village place in the coastal area in Gulf of Thailand, South of Bangkok. Long time age, this place was act as the sea port for Chinese Junk boat to come and exchanging thing. There are the evidences to support the idea such as old ceramic plate from China during the Ayutthaya period to now. The coastal erosion has started since 1977 and even maybe it has a sign of stated the event before. Coastal erosion problem has consumed land of the village which is next to the sea little by little. At first, villager were not concerned about it until the sea get closer than it usual being, so the villager has to move toward the land and let sea consumed the part of village.in 1994, the situation was getting worse, so that the villager has to come up with the plan in order to prevent the problem from getting bigger than this nowadays. They had come up with different method, but none of them are work perfectly. The main problem we must say is disappearing of mangrove forest, to become the uses land by the villager and developed land to be shrimp farm. If this problem keeps continuing, there will be no more for this village to exist.
In order to prevent those problems, we have to come up with the project to prevent the problem. One of the projects is already invented by one of the organization and university uses the concrete pillar specially design look like triangle to reduce the wave power and can make the dirt and sand in the wave separately form and leave it on the land. With those methods, when the sea wave come and release the sand on the ground, the land will form up and people will have land back.
