| Abstract: | Water hammer protection plays a key role in the engineering safety of long-distance water delivery.Hydraulic transients of long-distance water delivery system of Lijia River reservoir was calculated by using characteristic method.The amplitude variation of pressure raising and reducing to water hammer was investigated while opening and closing the lowest and interstage valve of pipeline with the same duration.The results showed that the controlling interstage valve of pipeline is the optimum scheme for wate... |
