| 摘 要： | 通过分析近期渭河下游河道淤积及河槽萎缩的特点,探讨了华县平滩流量变化对来水来沙的响应关系,从而给出了要维持渭河下游2003年汛后2500m3/s的平滩流量需要的水量和水沙搭配的定量关系。可对渭河流域综合治理提供一定的参考。

| Abstract: | The sedimentation in the lower Weihe River and the shrinking characteristics of the channel are analyzed in this paper. The response relation between the bank-full discharge and the annual runoff and sediment load has been also discussed .To maintain the bank-full discharge of 2 500m3/s (as the value in post-flood season of 2003 at the Huaxian station) in the lower Weihe River, quantitative relationship of the bank-full discharge to the runoff and the combined coefficient of runoff-sediment is presented in the paper. The result may provide a reference for the integrated management to the Weihe River basin. |
