Abstract: Although canal control automation has been generally disregarded in the irrigation modernization projects in Spain, regulation reservoirs formed part of most projects. Recent projects combining storage reservoirs with ...

Abstract: Flumes and weirs are hydraulic structures used to measure soil erosion and runoff at the outlet of agricultural catchments. Long-throated flumes use critical flow theory to determine discharge from a single water depth ...

Abstract: There is renewed interest in developing calibration methods for gates operating in submerged conditions in irrigation canals. In the present study, a new method based on a generalization of the standard energy-momentum ...

Abstract: Submerged sluice gates may be used as discharge measuring structures in irrigation channels. One commonly used model to predict discharge under submerged gates is based on the simultaneous solution of the energy and momentum ...

Abstract: Four rectangular sluice gates were calibrated for submerged-flow conditions using nearly 16,000 field-measured data points on Canal B of the B-XII irrigation scheme in Lebrija, Spain. Water depth and gate opening values ...

Abstract: The controllability of an irrigation canal depends on its physical characteristics, on the control algorithm used, and on the actual condition of the canal in relation to the algorithm tuning conditions. The flow conditions ...

Abstract: The area irrigated by furrow irrigation in the United States has been steadily decreasing but still represents about 20% of the total irrigated area in the United States. Furrow irrigation sediment loss is a major water ...
