Method to prevent the problem
The method to uses to prevent the coastal erosion on the Ban Khun Smuth Chin village is increase the length of the concrete pillar, extend the line along the coastal area and set it as 2 sections. Firstly, the pillar has to places along the coastal line at least 15-25 meters away from the land (sand area) and the other section is around 7-10 meters away from the first section (toward the sea). According to figure 1, black line is the 2 section for the pillar and the gray line on top is the old line that already set by village and organization, but for my method, I prefer to set the pillar along the coast line to form up the land and make the land up to where the temple places first. But also, we have to save the land and the temple form sea erosion. After the land has form up in front of the temple, we have to uses sea wall made of stone (red line). This is to prevent the sea wave from aside to erode the sand from the form of temple, and the wall also help to form up sand area and stabilize it, which can make villager can grow mangrove tree on this area to help land withstand the wave as well.
After set up the pillar on the area above, when sea wave come to pillar, its power will be reduce, so the damage to coastal area will be less, but if we set it 2 section, the damage from wave will be reduce around 80%, and dirt that come along with the wave will be leave on the impact area (land and pillar). That dirt will gather up for period of time and will naturally form up land. After the land has form up, the villager has to grow more mangrove tree on those areas to make the land form up strongly and can withstand the wave as long term prevention.
