The change of hydrological situation and the operation scheduling of the downstream of the hub make the water level at the inlet and outlet of the fish channel change at all time, and the fish channel is running improperly. The insufficient inlet water depth will cause water drop and hinder the backtracking of fish. The integrated model was used to analyze the hydraulic characteristics under different water level combinations at the inlet and outlet of the fishing channel. The results show that the hydrodynamic changes of the fish tunnel tank chamber are mainly concentrated in the pool chamber near the inlet, and the greater the influence is closer to the downstream. When the inlet water level decreases, the water drops at the inlet and it is difficult for fish to trace; When the inlet water level rises, the inlet velocity slows down rapidly. In view of the design inlet flow velocity is 0.60 m/s-1.00 m/s, the maximum drop between the outlet of the fish channel and the inlet water depth is recommended to be controlled at 1.00 m. At the same time, appropriate water replenishment measures should be taken according to the water depth of the inlet to form effective lure flow rate at the inlet, and there is a good linear relationship between the supplementary water flow and the inlet water depth.

枢纽下游水文情势的改变及运行调度使鱼道进出口水位时刻变化,鱼道运行不当,进口水深不足会造成跌水,妨碍鱼类上溯。采用鱼道整体模型,分析鱼道进出口不同水位组合下鱼道内水力特性变化特征。结果表明,受下游进口水位变幅影响,鱼道池室水动力变化主要集中在进口附近池室,且越靠近下游,影响越大。当进口水位降低时,进鱼口处出现跌水,流速出现极大值,鱼类难以上溯;进口水位抬升,流速迅速减缓,鱼道孔口设计流速为0.60~1.00 m/s,鱼道运行出口与进口水深最大落差建议控制为1.00 m。同时为在鱼道进口形成有效的诱鱼流速,需根据进鱼口不同水深采取适当补水措施,补水流量与进口水深存在较好线性关系。

枢纽下游水文情势的改变及运行调度使鱼道进出口水位时刻变化,鱼道运行不当,进口水深不足会造成跌水,妨碍鱼类上溯。采用鱼道整体模型,分析鱼道进出口不同水位组合下鱼道内水力特性变化特征。结果表明,受下游进口水位变幅影响,鱼道池室水动力变化主要集中在进口附近池室,且越靠近下游,影响越大。当进口水位降低时,进鱼口处出现跌水,流速出现极大值,鱼类难以上溯;进口水位抬升,流速迅速减缓,鱼道孔口设计流速为0.60~1.00 m/s,鱼道运行出口与进口水深最大落差建议控制为1.00 m。同时为在鱼道进口形成有效的诱鱼流速,需根据进鱼口不同水深采取适当补水措施,补水流量与进口水深存在较好线性关系。

The change of hydrological situation and the operation scheduling of the downstream of the hub make the water level at the inlet and outlet of the fish channel change at all time, and the fish channel is running improperly. The insufficient inlet water depth will cause water drop and hinder the backtracking of fish. The integrated model was used to analyze the hydraulic characteristics under different water level combinations at the inlet and outlet of the fishing channel. The results show that the hydrodynamic changes of the fish tunnel tank chamber are mainly concentrated in the pool chamber near the inlet, and the greater the influence is closer to the downstream. When the inlet water level decreases, the water drops at the inlet and it is difficult for fish to trace; When the inlet water level rises, the inlet velocity slows down rapidly. In view of the design inlet flow velocity is 0.60 m/s-1.00 m/s, the maximum drop between the outlet of the fish channel and the inlet water depth is recommended to be controlled at 1.00 m. At the same time, appropriate water replenishment measures should be taken according to the water depth of the inlet to form effective lure flow rate at the inlet, and there is a good linear relationship between the supplementary water flow and the inlet water depth.
