The check dams
built check dams sample activity
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
of the check dams
first. Help catchment
second. Reduces the incidence of severe wildfires
3. Reduces soil erosion. And reduce the severity of tidal creeks
four. Help keep sediment and other materials. The creek flows down to
five. Enhance biodiversity
6. The housing of the animals. And a water source CONSUMPTION
