Abstract:
In this paper, we took the middle route of South-to-North Water Diversion Project as an example, and built a one-dimensional emergency dispatch numerical model of the project. On this basis, we selected some typical canal sections as cases for simulation, so as to study the impact of target water level on the canal parameters (such as water level and discharge volume) in the process of emergency dispatch. The results showed that the target water level directly affected the amount of water discharge and the highest water level before the sluice. The higher the target water level, the higher the water level rise, but the smaller the water discharge volume. To improve the safety and economy of emergency dispatch, efforts should be made to increase the target water level before the sluice as much as possible under the premise of ensuring safety. This research can provide some reference for the contingency plans of the S-N project.
