通过对柳河沈彰新城段综合治理工程建设前后河流水文指标的计算分析,得出以下结论:工程有利于汛期河道行洪,造成的非汛期水量损失仅占同期多年平均径流量的2.85%;工程运行后对本河段泥沙淤积基本没有影响;河段最小生态基流约为0.9m~3/s,工程建设不会对河道生态流量造成明显影响。
Through the calculation and analysis of the river hydrological indicators before and after the construction of comprehensive management of Liucheng New City segment, the following conclusions are drawn: The project is conducive to flood discharge in the flood season, resulting in only 2.85% of the average annual runoff in the same period; After the operation, the sediment deposition in this section has basically no effect; the minimum ecological base flow in the reach is about 0.9m ~ 3 / s, and the project construction will not significantly affect the ecological flow in the river.
