标准范围

ISO 26906:2009规定了鱼道与流量测量结构集成的要求。它确定了具有令人满意的水文校准数据的鱼道，并给出了计算组合流量和不确定性的方法。注:测量构筑物和鱼道具有内在不同的水力性能标准。水测量结构在均匀流型下表现更好；相反，水流条件的可变性使鱼类和其他水生生物能够选择最符合其运动模式的通道条件，从而改善了鱼类的通过性能。ISO 26906:2009不建议讨论的鱼道是首选的通过方法，也不建议它们足够好，以至于可以牺牲通过性能，以获得一个同时具有这两种功能的单一结构。

ISO 26906:2009 specifies requirements for the integration of fishpasses with flow measurement structures. It identifies those fishpasses which have satisfactory hydrometric calibration data and gives methods for computing combined flows and uncertainties.NOTE Measurement structures and fishpasses have inherently different hydraulic performance criteria. Water measurement structures perform better with uniform flow patterns; conversely, fish passage performance is improved by the variability of the flow conditions that allow fish and other aquatic inhabitants to select the passage conditions that best meet their mode of movement. ISO 26906:2009 does not suggest that the fishpasses discussed are the preferred methods of passage or that they are good enough that passage performance can be sacrificed to obtain a single structure that does both.
