A check dam is a small, sometimes temporary, dam constructed across a swale, drainage ditch, or waterway to counteract erosion by reducing water flow velocity. [1] Check dams themselves are not a type of new technology; rather, they are an ancient technique dating from the second century AD. [ 2 ]
Bijapur Dam is situated in the Garhi Cantonment area of Dehradun, Uttarakhand, India. [1] The Bijapur check dam [2] was built on the Tons river close to Karkuli valley by Britishers in the year 1841, witnessing the civil engineering proficiency of British official Sir Proby Thomas Cautley, who worked on this one of the oldest check dams in Uttarakhand to improve the water supply in the region.
[3] [4] The check dams allow the aquifers to be replenished during the monsoon, so that bore wells and hand-pumps are recharged. [4] Villagers have been able to grow up to three crops per year and keep livestock. [1] [3] [4] Ruia estimates that the resulting increased income gives a 750% return on the investment in the check dams.
Amekawa Dam (Japanese: 雨川ダム) is a check dam on Ame river in Saku, Nagano Prefecture, Japan. The primary purpose is reducing water flow velocity to counteract erosion. The primary purpose is reducing water flow velocity to counteract erosion.
All rivers with average discharge more than 15,000 cubic feet per second are listed. Estimates are approximate, because data are variable with time period measured and also because many rivers lack a gauging station near their point of outflow.
The method consists of filling the flow area with stream and equipotential lines, which are everywhere perpendicular to each other, making a curvilinear grid.Typically there are two surfaces (boundaries) which are at constant values of potential or hydraulic head (upstream and downstream ends), and the other surfaces are no-flow boundaries (i.e., impermeable; for example the bottom of the dam ...
A check dam has been constructed upstream of the main reservoir on Sungai Bertam. The check dam is able to reduce the amount of sediment entering the reservoir and prolonging the reservoir life. A desanding system has been constructed at the intake of Sungai Telom for the same purpose. [4]
An anicut (Originated from Tamil language அணைக்கட்டு - Aṇaikaṭṭu and Kannada language ಆಣೆಕಟ್ಟು - Āṇekaṭṭu) and also in Telugu language as ఆనకట్ట - ÃnaKaṭṭa, is a masonry check dam that is constructed across a stream to impound water for maintaining and regulating irrigation. [1]
