The measurement and storage of tidal energy. Thailand has concluded that the height of the full tide of the day along the coast of Thailand and river waters. Areas with different levels of tidal energy quite higher than other areas of the estuary Ranong water up to a maximum of about four meters, the average year-round water up to about two meters lower than that, used to produce electricity. Thus energy development, tidal energy in Thailand do not have the education and research. Because of the different levels of tidal energy in the water of Thailand is the height of the water level is quite low.
