黄河下游河道平滩流量变化及其与汛期水沙条件的关系OA北大核心CSTPCD
Variation of bankfull discharge and its relationship with flow and sediment conditions during flood season in the Lower Yellow River
采用实测资料分析的方法,研究了黄河下游河道平滩流量变化与汛期水沙条件的关系.黄河下游河道平滩流量的变化是先减小后增大,由20世纪中期的7 000～9 000 m3/s减小到20世纪末期的2 000～4 000 m3/s;21世纪后,平滩流量恢复至4 000～7 000 m3/s.2000年前孙口平滩流量与汛期水沙条件关系点群与2000年后两者关系点群存在明显分区,表明小浪底水库蓄水拦沙运用后,下游河道冲刷演变机理与前期河道淤积演变机理存在较大差异…查看全部>>
Based on measured data,the variation of bank-full discharge and its relationship with flow and sediment conditions during flood season in the Lower Yellow River was analyzed.The result shows that the variation trend of bank-full discharge in the Lower Yellow River is first decreasing from 7 000～9 000 m3/s in the mid-20th century to 2 000～4 000 m3/s in the late 20th century,and then increasing to 4 000～7 000 m3/s in the 21s1 century.The established relationsh…查看全部>>
