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. Construction cost, depending on the size of the Creek, which should have no more than 4 meters in width.The benefits of slowing the water Dept. 1. help the entrapped water.2. help reduce the severity of the occurrence of forest fires.3. helps reduce soil erosion and reduce the severity of the water flow in the Creek.4. help retain sediment and materials that flow down to the water in the Creek.5. help increase biodiversity6. as of animal habitats and the use of water as a water source to the consumer.
