Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references (page 9). "Increased awareness of river pollution and the importance of water quality monitoring has made it necessary to improve the accuracy of discharge measurements. One of the factors contributing to the error in a flow velocity measurement is the uncertainty in the current meter calibration itself; This uncertainty must be determined experimentally. In this report, repeated calibrations of ten Price winter current meters, obtained in the towing tank of the Hydraulics Laboratory at the National Water Research Institute-, are examined to determine the uncertainty in their repeatability at the 99% confidence level. The results provide important information for the development of data quality control standards by the Water Survey of Canada for measurement of flow in rivers with solid ice cover"--Management perspective.
