摘要
2022年新孟河工程首次启动抗旱调水试运行,通过构建新孟河工程水文水动力模型,分别对界牌水利枢纽不引江和界牌水利枢纽按200 m3/s引江情景进行模拟,对比分析不同引江规模下洮滆片代表站点水位变化情况。结果表明,区域代表站点水位变幅和新孟河工程引水呈现较强的空间相关性,采用实况引江规模可以较大幅度抬升洮滆片区河网最低水位,若继续增大引江规模,对区域河网低水位抬升效果不明显,最高水位大幅抬高后易造成防洪风险,进一步验证抗旱调水试运行方案中确定的引江规模的科学性与合理性。
In 2022,the Xinmeng River Project started the trial operation of water transfer for the first time.In this paper,by constructing the hydrological and hydrodynamic model of the Xinmeng River Project,the water level change of Taoge Area representative site under different river diversion scales for the scenarios of no river diversion at the Jiepai water conservancy hub and river diversion at the Jiepa water conservancy hub according to 200 m3/s are simulated and compared respectively.The results show that the regional representative water level site variation and the Xinmeng River Project diversion presents strong spatial correlation,using the actual river diversion scale can raise the lowest water level of the river network in Taoge Area more greatly.If further increase the river diversion scale,the effect of raising the low water level of the regional river network is not obvious,the highest water level is easy to cause flood control risk after raising substantially,which further proves that the river diversion scale determined in the drought relief water transfer trial operation program is scientific and reasonable.
