Abstract: Excessively high or low pressure within an irrigation system can result in damage to pipelines, pumps, valves, and on-farm facilities. Frequently, these pressure variations are caused by a pressure surge resulting from a power failure, pump startup, or rapid valve closure. Numerous techniques are available to design engineers for predicting the magnitude of the pressure variations. If the analysis indicates potential problems, the designer should incorporate appropriate surge control devices into the system. Several of these devices are discussed and compared in this paper.
