引黄对内河河道淤积影响的初步分析

The Analysis of the Influence of the Yellow River Diverting on River Sediment Accumulation

本文确定以东鱼河、洙赵新河为研究范围，该范围内含六个引黄灌区。根据有关的实测资料，依据沙量平衡原理，先分析求得河道淤积量、河道输沙量、引黄尾水入内河的沙量和当地产沙进入河道的沙量，然后再进一步作淤积成因的分析，从而得出引黄对内河河道淤积的影响程度。

This paper makes a study on the sedimentation in the Dongyu River and Zhuzhaoxin River.Thisregion covers 6 irrigated areas by diversion of the Yellow River On the basis of the sediment balance principle,with the observed data.we firstly calculate and analyse river deposit,river sediment discharge,sediment from the Yellow River and sediment yield、and then analyse the reason of sedimentation,so that we can make a conclusionhow the diverted water from the Yellow River influence the sediment accumulation in the inland rivers.
