| 520 | |a"Work conducted in other countries in the 1960's demonstrated the feasibility of using acoustic velocity measurement devices for determining flow in open channels. Accordingly, a decision was made to install one such instrument, the Westinghouse Leading Edge (LE) Flowmeter, on a large Canadian river where there was a demand for "real time" streamflow data and where the stage-discharge relationship was affected by backwater. Results obtained would be used to determine the feasibility of operating an acoustic streamflow measurement system under Canadian conditions. A flow meter having a 1700-foot (530-metre) long acoustic path was installed in 1971 and, despite some installation and operational problems, is providing accurate streamflow data. The plans for the future include telemetry of the data to users and further calibration of the instrument"--Abstract, p. vii. |
