A dam project along the nickname maeo initiative about folk design engineering. Weir is a Weir for water softening maeo semi-permanent one category. The only category with a brood of pigs by using materials that Weir is available locally, such as simple twigs. Rocks to slow the water barrier in the stream or water flow is slow and small, trapped in an area long enough to be absorbed into the surrounding area will be used as a refreshing forest degradation result in moist enough to develop into a complete jungle. Weir may also be used for irrigation maeo, levels high enough to pull water into the canal water in the dry season. The project, along with the initiative this evaluation projects, Huei Hong Krai, and successful so far is an example to other projects later. Weir water created slowing across small streams of water flow on to slow the flow of water-flow-reducing violence. Reduce bank erosion-wash water flows more slowly when it has water in it, especially in front of Lam drought-aid trap sediment flowing with water. Reduce the downstream shallow clear water makes better-quality allows the soil treatment. There are an abundance of forest. Increase biodiversity-aquatic animals lived in the life Return unto the hills/mountains, plants, head of soil humidity, rain forest-lon made the forest fire severity of the light. To protect your forest and bathed in chuen catchment The way the project has prepared a water softening the water Weir stream 2 and to build understanding. For the projects that we have to slow down a dam made of its purpose and the method of construction to minimize the impact on ecological systems. In the long run, as follows: 1. Weir is a weir which we created a non-natural materials, primarily for slow water. Only in the dry season. Not new to catchment The flow of water at the dam is a water flow. At any time, regardless of whether the water is absorbed through the overflow weir Weir, or cross- 2. the height of the Weir It is not very high. Approximately 40% of the height of the height of the highest water level. In canals or Lam Water can also flow through the overflow weir. At any time, to preserving ecological system. In front of Weir. 3 the Weir should be approximately level slope 20-45 degrees both in front and behind. Should not create a dam that is in front of the cutting ๙๐°. 4. The construction will create a wide wide stepped up close to the stage area about 200 meters ๕๐-4 construction budgets, we are just barely stone rake ringed by canals come close by raka rearrange only is exercise. If there are no stones, we will use the sack. ๕. หากหน้าน้ำ มีน้ำมา ฝายนี้ก็จะพังทลาย ลง (ช่วยลดความเร็วของกระแสน้ำป่า ลงได้) หินที่ก่อเรียงตัวไว้ ก็จะพัง และ ไหลลงมาสู่ตัวฝาย ด้านล่าง ต่อไป ๖. พอหมดหน้าน้ำป่า น้ำเกือบจะใกล้แห้ง เราก็หาเวลามาออกกำลังกาย มายกก้อนหินกลับไปเรียง เป็นฝายชะลอน้ำ ตามเดิม (ส่วนใหญ่แล้ว จะยังหลงเหลือ โครงสร้างเดิมอยู่บ้าง) ใช้เวลาก่อสร้าง ประมาณ ๑-๒ ชม. ต่อฝายเท่านั้น ๗. ควรคำนึงถึง สัตว์น้ำ ที่อาศัยในลำคลองด้วยว่า สามารถเดินทางไปยังต้นน้ำได้หรือไม่ เพราะเราตั้งใจว่า “ในน้ำต้องมีปลา ในป่าต้องมีน้ำ
