On the basis of monitoring results of water quality and benthos, the impacts of two generic bulk berths construction in Nantong Port on downstream water quality of water intake were analyzed.
Wetlands can be designed to provide very important downstream water quality benefits.
湿地设计对提高下游水体质量十分有利。
It's mainly used to fully or partially open water -flowing orifice of hydraulic construction to adjust the upstream and downstream water level and flow.
主要用于全部或部分开启水工建筑物过水孔口的大小,起到调节上下游水位和流量的作用。
It is found that three patterns may occur to the flow in the pool including free impact jet, submerge impact jet and surface flow according to the downstream water level.
根据高坝下游水垫深度的不同,塘内水流呈现自由沖击射流、淹没沖击射流和面流三种流型。
With the upstream water level reducing and the downstream water level increasing, the highest tangent velocity also moving to the pipe center.
随上游水位的降低及下游水位的升高,切向流速最大值点也不断向管中心一侧移动。
The bigger the downstream water level, the outstanding of variation degree of axial velocity along radius distribution when upstream water level is same.
下游水位越高,变化相同的上游水位时,轴向流速沿径向分布的变化程度越大。
The vacuum degree at tailrace adit varies most significantly at the lowest downstream water level and improves gradually along with the rising of downstream water level.
