Ano: 1965 URL: http://eprints.nwisrl.ars.usda.gov/1242/1/19.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.
