Ano: 1970 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: 1987 URL: http://eprints.nwisrl.ars.usda.gov/876/1/601.pdf Automation Playing Key Role in Surface Irrigation Interest NWISRL Humpherys, Allan. Surface irrigation is receiving increased attention because of its low energy requirements and cost. Current improvements are aimed at reducing the amount of labor required and increasing system efficiency. Researchers at the USDA's Snake River Conservation Research Center in Idaho are developing new and improved irrigation techniques and equipment to achieve these objectives. These improvements use automation in one form or another along with accessory equipment such as trash screens and energy dissipaters.
