Abstract: A project is currently underway to evaluate the performance of 27 acoustic flowmeters used at Hoover, Davis, and Parker Dams on the lower Colorado River. Field surveys and laboratory testing are being used to evaluate and enhance the performance of the chordal-path acoustic velocity meters. A hydraulic model and a laser doppler anemometer are being used to determine velocity distributions for the nonstandard flowmeter installations.
