Abstract:

The method of discharge computation for a single tide is generally adopted in the calculation of water diversion amount for tidal sluice. But the method requires long time and large work load. Especially for sluices with changing gates, the measwrement and calibration are burdensome. With Dingbo sluice in Wuxi City as a research case, the authors proposed a novel method of calculating the water diversion amount which is based on hydraulic formula to analyze the waterhead-flow relation. Result shows that the calculation accuracy meets the specification requirements. The method is convenient, feasible, and accurate for the statistics of water diversion along the river, and could provide data for the most stringent water resource management regime.
