摘要
文章基于嫩江下游河流水文特性,针对水位流量过程变化和洪水传播特点,采用上下游结合,对2010年的水位流量关系做了系统分析。结果表明:大赉站水位流量关系受下游洪水顶托影响复杂多变,是嫩江和松花江水流相互影响制约造成。受其影响,大赉站落差大时流量变化大,落差小时流量变化小。
Based on the hydrology characteristics of Nenjiang river downstream,the paper analyzes the stage-discharge relation of 2010 according to the change of stage and discharge and the characteristics of flood transmission and situation with the upstream and downstream.The results show that the jacking influence of downstream flood on stage-discharge relation of Dalai station is complex,which is caused by the mutual restriction and influence of water flows of Nenjiang river and Songhuajiang river.The discharge change larges with the water level falling increases,otherwise it will smaller.
