摘要变动回水区河段设计最低通航水位确定是目前山区航道整治工程中经常遇到的问题。 - Taking the reach with fluctuating backwater area in jiaokou hydroplant in xiujiang river , guanxi zhuang autonomous region for instance , this paper analyzes the water - sediment characteristics of the fluctuating backwater area , calculates the design level of this reach with samples of level and discharge , etc . , and propounds the determination method for the designed lowest navigable level of reach with fluctuating backwater area
以广西绣江交口电站的变动回水区河段为例，分析了变动回水区的水沙特性，分别利用水位、流量样本及不同方法计算与分析本河段的设计水位，提出了变动回水区河段设计最低通航水位的确定方法。 - Shipment traffic usually is heavy in littoral area , the navigation capability is required in many riverway . navigation lock was set to suit for the water level ' s variety caused by tide . for a long period , being lack of the quantified assessment on the influence of saltwater intrusion , approaches that freshwater is inpoured to the lock chamber are adopted lest the high concentration salt water be imported to the inland waterway , when the navigation lock is in operation . but such manner should not be reasonale enough
沿海地区船运发达，很多河道有通航要求，为克服潮汐造成的水位变化而设置船闸。长期以来，由于缺乏对盐水入侵内河河道产生影响的定量评估，在船闸运行过程中为防止高盐度咸水入侵内河，通常采用将内河淡水打入闸室的方式来调节通航水位，船闸的这种运行方式不尽合理。
