Summary

 

An index velocity rating was developed for a SonTek/YSI Argonaut Side-Looking (SL) ultrasonic Doppler flow meter installed in the Main Canal of the Colorado River Indian Tribes (CRIT) Irrigation Project in Parker, Arizona.  Velocity data collected concurrently with the ultrasonic flow meter and conventional current meter were compared using linear regression techniques.  The rating equation for this installation provides a reasonably accurate means of computing discharge.
