Outline on River Regulation of the Yellow River in Ruicheng Stretch in Sanmenxia Reservoir Area

黄河三门峡水库潼关至大坝河道长113.5km ,其中芮城段67 .2km ,按水库运用情况,黄淤41 ～30 断面长45 .6km ,河道特性明显,称为自然河道段;黄淤30～24 断面,长21 .6km ,呈水库和河道双重特性,称回水变动段。经对两段河道特性和多年流势分析及已建护岸工程的基本评价后,本文对工程设防标准、基本流路。

Through the analysis of the features of river and flow regime of the Yellow River in Ruicheng stretch in sanmenxia reservoir area and the evaluation of the built bank protection works,clata for,the flood control standard,basic flow path,plane layout,and structural form for the river regulation works are given,which are feasible and tally with the integrated planning.
