摘要: 一些大型水电工程的建设和运行,使流域径流时空分布特征产生了一定变化,尤其对下游水文站的实测径流、洪水资料系列的一致性有一定影响。应用此类水文资料时,需将受影响水文资料还原至天然状况。以大渡河中游毛头码水文站为例,对该站1987~2014年的实测径流、洪水资料的一致性进行分析,并采用水量平衡方法进行一致性还原计算。计算结果表明,采用水量平衡法还原的毛头码站径流、洪水系列具有一致性,可用于相关工程设计。

Abstract: The construction and operation of large hydropower projects will change the runoff spatial and temporal distribution, especially the consistency of measured runoff and flood data at the downstream hydrological station. Taking Maotouma Hydrological Station in the middle reaches of Dadu River as an example, we analyzed the consistency of the measured runoff and flood data from 1987 to 2014 and converted it to natural condition by water balance method after the operation of Pubugou Hydropower Station. The results show that the converted runoff and natural data are consistent with the nature and can be used in engineering design.
Key words: hydrological data, consistency analysis, water balance method, Maotouma hydrological station, Pubugou Hydropower Station
