Última Water Control and Measurement on the Farm NWISRL Robinson, A.R.; Humpherys, A.S.. Tipo: Book Section Palavras-chave: Irrigation control; Research methodology; Mass Import - autoclassified (may be erroneous). Ano: 1967 URL: http://eprints.nwisrl.ars.usda.gov/730/1/66.pdf Automatic Water Control Structures for Surface Irrigation (Summarized) NWISRL Humpherys, A.S.. Many improvements have been made in irrigation methods and equipment in recent years. However, surface irrigation has not benefited from automation and still requires much hand labor. In addition to this high labor requirement, an excessive amount of water is often used. This is particularly true in areas where water is relatively cheap and labor is scarce. Further improvement in surface irrigation methods and equipment using mechanized automated control structures will enable the farmer to apply water with a minimum of labor and to obtain maximum use from the water, thus conserving his resources.

Ano: 1988 URL: http://eprints.nwisrl.ars.usda.gov/493/1/645.pdf Cast-in-Place 2-Foot Concrete Trapezoidal Flow-Measuring Flumes NWISRL Humpherys, A.S.; Bondurant, J.A.. Procedures are presented for casting 50-ft^2/sec trapezoidal water measurement flumes in 2-foot bottom width lined and unlined ditches. Drawings and construction details for the concrete forms used are also presented. Flumes installed in concrete-lined ditches require about 13 man-hours and cost about $230. Flow can be determined for both free and submerged flow conditions from rating tables with depth measured in a sitting well or with a sloping gage on the flue sidewall.
