Abstract: Control schemes which are available for the operation of canal networks for irrigation projects are examined. These control schemes include upstream control, downstream control, controlled volume control, dynamic regulation, ...

Abstract: Calibration equations for free-flowing radial gates typically provide sufficient accuracy for irrigation district operations. However, many water purveyors have difficulty in determining accurate discharges when the ...

Abstract: Laboratory studies are conducted on a rectangular broad‐crested weir to determine the effects of entrance and exit conditions on the discharge and required energy loss. In doing so, a method for visually determining whether ...

Abstract: Good water management in irrigated agriculture requires that irrigation water be accurately measured. Presented herein are design procedures and rating tables for modified broad‐crested weirs (which act hydraulically as ...

Abstract: Tests were conducted to study the effects of nonlevel placement or construction on the calibration of long‐throated flumes. These flumes have previously been mathematically modeled to provide accurate

Abstract: A new approach to the design of flumes and weir for open channels is developed. The approach is based on matching the flume to approach channel conditions thus providing an appropriate Froude number in the approach channel ...
