field to check for potential inaccuracies during collection is remarkable ,” Armstrong said of the ADCP system . “ This instrumentation is a much more accurate way to measure discharge and easily adaptable to a variety of environments .”

resources engineer at Ayres . The Ayres team used an Acoustic Doppler Current Profiler ( ADCP ), which allows for measurements that can be taken from the banks , is much less time consuming and provides more accurate results than traditional methods .
The instrumentation Ayres used was the SonTek RS5 , regarded in the industry as being the most compact and robust ADCP system on the market . The system is mounted on a custom-designed board that resembles a boogie board . It allows users to
quickly collect high quality water velocity and flow measurements in a variety of environments . Cross-section measurements were set up using mounted T-posts on each side of the ditch , with a rope and pulley system that allowed the instrument to be pulled back and forth across the stream . The real-time data is sent to a field laptop via Bluetooth . Specialized software is used to collect and analyze the data .
“ The whole system is pretty slick . From the general portability to being able to see live measurement data in the
Using this equipment , Ayres engineers measured flow in the fall of 2022 at three cross-sections : one at the most upstream section of the canal where the water enters the system , one in the middle of the canal located after the sediment pond intake , and the last one at the end of the canal downstream of the Pleasant Valley Pipeline inlet . Based on the results , Ayres engineers concluded that the loss was contained to about 500 feet of the Munroe Canal and adjacent sediment basin .
