Slowing the water Dept.From the theory of the development of forest restoration due to the initiative. By the use of water resources, maximize the benefit by building defensive fire, wet (Wet Fire Break) is one such method is to build a Weir, retard moisture called Check Dam to block channels or streams intermittently small catchment, soil and sludge. By the water stored will absorb accumulated in soil. Make the moisture expansion into both sides of the water becomes wild wet (chaipattana Foundation, 2555) a Special Commission to coordinate the project due to the initiative (kapon) (2550 (2007)) say that Weir Weir upstream water bump. Weir River FAI MEO or delaying the moisture difference, however, is the same thing. Called by the English that the Check Dam building is obstructed or barrier of the river and from meeting 1/2547 (2004) kapon. have been listed on the agenda of our order urged his Majesty about the construction check dams, according to Huay Hong Krai development study centre due to the initiative Amphoe DOI Saket, Chiang Mai Province that should be extended to cover all areas.From such flows have both public and private sector agencies. Projects in thousands of check dams Weir The objective is to slow down the flow) to reduce the severity of the water flow and reducing erosion of the bluffs, 2) allows the water in the Creek is long, especially during the dry season 3) help trap sediments to minimize shallow water at the tip. Make the water clear and better 4) allows the soil moist. Wild abundance. Biodiversity, animals, water and wild animals live in the water, life, social night, scrapping the plant 5) Hill/mountain 6) moist soil, the bald, it becomes moist forests. reduce the severity of forest fires.Therefore, in order to check dams, best all parties and the negative impacts on the environment, both in the original ecosystem, and various creatures that reside in the area. Is very important to have a detailed study to be able to choose the type, or format, including how to build a Weir Weir at the appropriate areas and factors in both living organisms and physical factors in the area and make the water Weir delaying benefits.
