标准简介：This International Standard 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. This International Standard 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.
