摘要

摘要低水位河流穿越和涵洞为社会提供了宝贵的运输和水力控制服务,但对上游鱼类通道产生了负面影响。最近,澳大利亚东北部实施了全高侧壁挡板,以帮助小型鱼类在箱形涵洞中向上游通过,尽管对涵洞排水能力的影响被忽视了。详细的物理建模是在控制流量的条件下,在一个接近全尺寸的涵洞桶形通道中进行的,该通道配备了这种全高侧壁挡板。研究结果为全高侧壁挡板对箱涵泄流能力的影响提供了定量评估。开发了单孔和多孔箱涵的应用,并讨论了实际意义。

How full-height sidewall baffles affect box culvert capacity: balancing fish passage and discharge requirements
ABSTRACT Low-level river crossings and culverts deliver valuable transportation and hydraulic control services to the society, but have negative impacts in terms of upstream fish passage. Recently, full-height sidewall baffles have been imposed in north-eastern Australia to assist upstream passage of small-bodied fish in box culverts, although the impact on the culvert discharge capacity was ignored. Detailed physical modelling was conducted under controlled flow conditions in a near-full-scale culvert barrel channel, equipped with such full-height sidewall baffles. The results provide a quantitative assessment of the impact of full-height sidewall baffles on the discharge capacity of box culverts. Applications were developed for single- and multi-cell box culverts, and practical implications are discussed.

期刊介绍: The Australasian Journal of Water Resources ( AJWR) is a multi-disciplinary regional journal dedicated to scholarship, professional practice and discussion on water resources planning, management and policy. Its primary geographic focus is on Australia, New Zealand and the Pacific Islands. Papers from outside this region will also be welcomed if they contribute to an understanding of water resources issues in the region. Such contributions could be due to innovations applicable to the Australasian water community, or where clear linkages between studies in other parts of the world are linked to important issues or water planning, management, development and policy challenges in Australasia. These could include papers on global issues where Australasian impacts are clearly identified.
