水库回水计算是确定水库淹没范围，进行规划方案论证的基础工作。

Calculation of backwater in reservoir is foundational for defining inundated area in a reservoir and demonstration a planned program .

水库回水末端判别标准的精度不仅影响回水长度的大小，在有些情况下甚至影响回水长度随流量变化的规律；

Criterion for the terminal of backwater may have effect not only on backwater length , but also on the rule of backwater length ′ s fluctuation with discharge .

由于河道型水库回水情况与一般水库有较大的差异，因此不能采用常规的回水计算成果来确定水库的淹没范围。

Since there is a larger difference between backwater in river-run reservoir and in the general one , the results of the conventional calculation of backwater can not be used to define the inundated area of a river-run reservoir .

潼关断面位于黄河和渭河汇流区下游，由于受三门峡水库回水淤积和近期黄河来水减少等因素的影响，致使近年来潼关高程持续上升且居高不下，给渭河下游防洪带来了较大危害。

Because of backwater deposition of the Sanmenxia reservoir and reduction of incoming water of Yellow River and so on , Tongguan riverbed continued to raise high in recent years , and it has brought large hazards to flood control in lower reaches of Weihe River .

重庆主城区河段处于三峡水库变动回水区，又是嘉陵江汇入长江的河段，水流条件和泥沙运动十分复杂。

The reach of Chongqing City is in the variable backwater region of Three Gorges Reservoir , and it is also the reach as the Jialingjiang River flowing into the Yangtse River .

三角洲河道动床之自我调整作用，因水库水位之回水影响，其输沙特性有异于明渠均匀流。

The sediment transport resulted from self adjustment of the channel bed due to backwater effects differs from that occurring in a uniform flow .

按照这一方案运行后，重庆主城区河段将位于三峡水库的变动回水区，其冲淤情况变得更加复杂。

The river reach in Chongqing downtown lies in the fluctuating backwater region , after running on the 175m scheme of the Three Georges Reservoir , the process of sediment deposition and scouring condition becomes more complex .

开始蓄水拦沙运用，水库严重淤积回水迅速上延，引发设计输沙量和水沙综合调节治河新理论。

During the operation of storing water and retaining sediment , serious deposition in the reservoir leads to backwater level rising rapidly . Therefore it also brings out new river-trained theory of design sediment load and integrated regulation of water-sediment .

河段糙率是计算水库、水电站回水和确定淹没搬迁线的重要参数。

The river reach roughness is a important parameter for calculating reservoir and hydropower station backwater and determining submerge and move line .

三峡水库建成后，重庆主城区河段处于水库变动回水区的中上段，其水动力条件和物质输运能力将发生巨大变化。

After the running of Three Gorges Reservoir , the reaches of Yangtze River and Jialing River in the city Chongqing become the middle and upper reach of the fluctuating backwater reach of Three Gorges Reservoir , and their hydrodynamic conditions will be changed greatly .
