One of the principles in forest conservation is to slow down the water Dept. working or slow down moisture, which means that building across the small river barrier in upstream areas, or areas with high slope so that water can flow to slow down the flow slowed and entrapped sediment to not go down to the lower river basin area. Type of dam water bump or retard moisture. Divided into 2 categories.1. upstream dam or weir retard moisture as water retention dam, flows slowly and can permeate into soil to create moisture surfaces;2. soil sediment trap Weir Sandy soil and sediment traps, Weir is not trickling down to the water below.The format of the Weir can be divided into 3 style. 1. locally or commonly known as the "Weir MEO" is a construction with natural materials like twigs. Flanking Driftwood with stones of various sizes in a Creek or ditch by sediment traps will be. Slow the flow of water and adds moisture the area around the dam. 2. a relatively permanent as stone construction with stone wall is sort of water. Construction of the central area and the lower part of the Creek or ditch will be able to trap sediment and water during the dry season, have some.3. reinforced concrete is the most permanent construction is performed in the area at the end of a Creek or ditch. Makes it possible to trap sediment and water during the dry season it well.

principle of the conservation of forest resources is making check dams. Check dams or moisture, which means building a barrier across the river in small watersheds. Or areas with high slope. The hot water can flow to slow down and trap sediment. In order not to fall into the lower watershed

of a weir or dam slow moisture divided into 2 categories
: 1. watershed dam. Check dams or moisture A catchment dam to flow slowly. And can seep into the subsoil. To create moisture to the surface area of the
two. Dams trap sediment, sand dams trap sediment, sand and water to flow into the lower

forms of the dam can be divided into three types
: 1. Local primary. Also known as "The cat" as construction materials are natural, such as tree branches, pieces of wood, bordered by a stone in the creek or ditch to trap sediment. Slow the flow of water and add moisture to the area around the dam has
2 stone tiles rather permanent. The construction stones lining a wall of water. Building in the middle and lower streams or ditches to trap sediment. And store water during the dry season, some
three. a reinforced concrete The construction of permanent Many are carried out in the area at the end of the creek or ditch. It can trap sediment And storing water in the dry season as well. Construction costs depend on the size of the creek. It should have a width of up to 4 meters

An irrigation project.The definition.Pre test.Solutions like test before class.Dam projects slow water.A project to build a dam to slow the water.One of the major of forest resources conservation is to do the weir weir water or slow slow moisture, which means that construction in small watershed in the river barrier Or areas with high slope. To make the water flow strength can to slow the flow slows down and retain sediment. In order not to go down into the river basin at the bottom.The type of weir or dam slow slow water moisture, divided into two types.1. The weir weir upstream or slow the moisture is a repository of dam water flowing slowly and can which milk under the surface. To create the moisture to the floor.2. The weir trap sediment, sand, a weir trap sediment and sand from flowing into the water below.The form of the weir can be divided into 3.1. A local elementary, commonly known as "check dam" is a construction material is naturally, such as branches, the rod. Flanked by stone of various size in the creek or ditch. It can trap sediment. Slow down the flow of water and add moisture to the area around the dam.2. A sort of rock is relatively fixed. A sort of stone wall construction with water. Construction of the middle and lower of the creek or raceway can trap sediment and retention น้ำในช่วงฤดูแล้ง partial3. The reinforced construction is permanent. Most will be conducted in the end of the creek or ditch. It can trap sediment and keep กักน้ำ in dry season. Construction depends on the size of the stream. Which should have the width not more than 4 meters.The advantage of the weir to slow the water.1. Help retain water.2. Help to reduce the severity of the wildfire.3. To reduce erosion of the soil. And reduce the severity of the tides in the creek.4. Helps retain sediments and materials flowing down to the water in the stream.5. To help increase the biodiversity.6. Is the habitat of animals and used as a water source for consumables.Sub pages (1): dam river.Comments.Signed singer
