Designing effective fish-friendly waterway culverts: integration of hydrodynamics and swimming performance

人为的溪流中结构(例如水坝和人行横道)导致本地鱼类数量大幅下降，仅新南威尔士州就有6,000多个障碍阻碍鱼类迁徙。认识到这一点，渔业新南威尔士州带头制定了设计和建设鱼类友好型人行横道的国家指南。不幸的是，这些指导方针几乎没有经验支持。该项目将把有关澳大利亚鱼类种类游动能力的数据与涵洞水动力模型相结合，以更好地了解道路交叉口内和周围的鱼类需求。这些数据将加强国家设计指南，并提供工程师和规划者需要的工具，以平衡鱼类迁徙和有效的水管理。

Man-made in-stream structures (for example, dams and road crossings) have contributed to major declines in native fish numbers, with more than 6,000 barriers to fish migration occurring in New South Wales alone. Recognising this, Fisheries New South Wales led the development of national guidelines for the design and construction of fish friendly road crossings. Unfortunately, these guidelines have little empirical backing. This project will integrate data on the swimming ability of Australian fish species with culvert hydrodynamic modelling to better understand fish requirements in and around road crossings. These data will strengthen national design guidelines and provide the tools engineers and planners need to balance fish migration with effective water management.
