What is the control dam?
The check dam is a small dam that can be built from a wide range of materials, including protocols, rocks and bags with sand, and can be used for various purposes, such as providing an area for sediment, mud or pollutants such as garbage and heavy metals to settle and remove from water. This type of dam can also be used to slow water flow and maintain water for purposes such as irrigation, fish breeding or livestock. Check the dams often built through drainage ditches, small streams or in marshy, low areas called swales. The recommended specifications for the control dam are that it should not be higher than 2 feet (60 cm), that the center of the dam should be at least 6 inches (15 cm) lower than the edges and that it should be used to drain the areas of 10 acres (0.04 km2) or smaller. The construction of the dam is often easy and cheap, which makes them practical in poor areas with several financial and technological sources.
in developing countries withThe dams often use to increase agricultural production, supplement groundwater and prevent soil erosion in heavy rainfall such as monsoons. Review dams can also be used in artificial drainage ditches called Bioswals, which are often designed specifically to remove pollutants from the water. The construction of the dam control varies depending on the material used for construction, but the material must be stretched across the channel, which is damaged, and often part of the material must be built into the soil to ensure that the dam remains in place even during heavy water flow.
Three common types of control dams are stone control dams, dams for checking rocks and protocol control dams. The rock control dam is usually built with 8-12 inches (20-30 cm), while the stone control dams are designed from smaller stones, usually 2-3 inches (5-7.5 cm) in diameter. The protocol check dam is created using 4-6 Pa protocolsLC (6-15 cm) in diameter and protocols must be buried in a salt to a depth of at least 18 inches (45 cm). Virgin bags are sometimes used to create dams of temporary checks, for example in the case of floods or very strong precipitation.
The check dam requires frequent checks, especially before and after heavy rainfall. The dam itself must be checked in terms of damage and wear and the sediment level behind the dam must also be measured. Such a sediment may disrupt the function of the dam and sometimes it must be removed or the dam may fail.
