River/Stream/Canal Discharge - Velocity Indexing

 Argonaut-SL |
 SL-ADP |
 Argonaut-SW |
 Argonaut-ADV |
The Argonaut-SL (Side-Looking) current meter, the Argonaut-SW (Shallow Water), and the Argonaut-XR (Extended Range) current meter are the primary SonTek/YSI solutions for velocity measurements in a velocity-stage indexing program.
The Argonaut-SL can be mounted on one side of the river and can project its sampling volume up to 120 m across the river. A vertical beam provides water level information. Note: For longer ranges, you may want to consider our side-looking Acoustic Doppler Profiler (SL-ADP).
The Argonaut-SW is bottom mounted and provides a depth-integrated velocity measurement out to a range of 5 m. A vertical acoustic beam provides water level information. The measurement cells will dynamically adjust in size as the water level changes. Typically used in irrigation canals.
The Argonaut-ADV is designed for gauging in rivers that are extremely shallow (a few centimeters), by providing a point measurement at a carefully chosen location.
The Argonaut-XR
(right) is designed for bottom-mounting
for measuring depth-integrated velocities out to a range of 40 m. An on-board
pressure sensor can be set to automatically adjust the measurement parameters with
changing water levels.
The Argonaut systems can be configured using the U.S. Geological Survey's SDI-12 protocol.

The USGS California District uses four Argonaut-SLs to obtain index velocities at four locations in the California Delta. Two of the SLs are mounted on the back side of wooden bridge fenders looking out from under the fender towards center channel. |
