Description of the SLM Technology
Short description of the Technology
Auto-flowing slurry dams is filled with dense slurry by water flow from upland to maintain eroded soil particles and runoff.
Detailed description of the Technology
Falling water filled dams distribute widely in the middle reaches of the Yellow River, they are used to store water and wrap sediment which result from soil and water loss. On the Loess Plateau, in addition to the conditions of deep gully and steep slope, earth above the top of the dams can be used to build dams. First, soil is loosed with squirt guns, exploded or manually dug. Then, water is pumped up to the loose earth so as to rush the soil down along transporting ditch, turning the soil into dense mud to dam level surrounded by tamped banks. Under the press of gravity, the mud dehydrates, consolidates and becomes uniformly dense body of the dams. Compared with dams in other areas, the water power filled dams in the Yellow River basin are characterized by much denser mud, uniform particles and body texture, smaller transect of dams body, and wide applicability to soil materials such as sand soil, loess soil and weathering residue. The types of dams have widely applied to build moderate and small reservoirs and silt arresters in the middle reaches of the Yellow River, they play an important role in increase in agricultural production and reduction of sediment into the Yellow River.
