摘要

水工结构破坏了鱼类的洄游,从而导致了世界各地鱼类数量的下降。用管道将鱼从水坝上引到上游的方法可以提供比传统的鱼道更大的升力。我们描述了一个管状鱼道的提升机制,用数值模拟演示,并通过物理模型验证。通过将两种澳大利亚本地鱼类安全提升到8米以上的堤岸,证明了其功效。大量的水可以通过简单的管道和两个阀门从大坝底部的一个腔室输送到大坝顶部。非定常流完全或显著地贡献了升水的体积。我们探索如何扩大这个管道系统,同时控制湍流对鱼类的影响。我们提出表征鱼道液压效率的新方法,认识到所使用的能源和排放的水的价值。

Piping fish over dams

Hydraulic structures disrupt fish migration thereby contributing to declines in fish populations around the world. Methods for piping fish upstream over dams can offer much steeper lift than conventional fishways. We describe the lifting mechanism of a tube fishway, demonstrated using numerical modelling, verified by a physical model. Efficacy is demonstrated by safely lifting two species of Australian native fish over 8 m up an embankment. Significant volumes of water can be transported from a chamber at the foot of a dam over its crest using simple conduits and two valves. Unsteady flow contributes entirely or significantly to the volume of water lifted. We explore how this piped system could be scaled up, while controlling turbulence impacts on fish. We propose new methods of characterising hydraulic efficiency for fishways that recognise the energy used and the value of the water discharged.
