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

人为的河流结构（例如水坝和公路交叉口）导致本地鱼类数量大幅下降，仅在新南威尔士州就有6，000多个鱼类洄游障碍。认识到这一点，新南威尔士州渔业局领导制定了设计和建造鱼类友好公路过境点的国家指导方针。不幸的是，这些指导方针几乎没有经验支持。该项目将把澳大利亚鱼类游泳能力的数据与涵洞流体动力学模型相结合，以更好地了解道路交叉口及其周围的鱼类需求。这些数据将加强国家设计准则，并为工程师和规划人员提供必要的工具，以平衡鱼类洄游和有效的水管理。

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.
