Flow monitoring site and hydraulic conditions that can impact a stable stage-discharge relationship comprises of unstable section control, sediment transport, debris, vegetation, off-channel storage, variable backwater effects and unsteady flow conditions.

But behind the massive tunnels and the huge catch basins is a system just as staggering – the SMART Project’s nerve system, a network of flood detection equipment and automated management machinery linked by a Supervisory Data Acquisition and Control (SCADA) brain that uses the information it gathers to automatically engage flood management gates and pumps.

HidroMares has installed its SISMO systems at seven port complexes around Brazil, from ocean terminals in the south to an inland river port in the Amazon basin. At the heart of each system is a SonTek acoustic Doppler current profiler (ADCP), which provides current velocity and direction data throughout the water column, as well as water level.

The ARC-Boat was developed by HR Wallingford and employs SonTek-proprietary Acoustic Doppler Profiler (ADP®) technology. The HydroSurveyor is a highly sophisticated system which includes 5-beam depth sounding, water velocity profiling and navigation capabilities. When mounted in the ARC boat, the HydroSurveyor scans the reservoir as it is guided across the water’s surface. Recorded data is then analyzed by HydroSurveyor software to produce accurate depth measurement in addition to bathymetry maps of the entire water body. With a small amount of post-processing in GIS or 3-D CAD, an accurate water volume can be determined.

The HydroSurveyor-M9 system from SonTek, a Xylem brand, is an instrument/technology that Indian Railway has employed to rapidly measure bathymetry data along with velocity data.

A shot seal would usually float, buoyed by its blubber atop the dense saltwater of Canada’s Hudson Bay.

The Bagmati is both a sacred river and a city sewer, running through Nepal’s capital city of Kathmandu before heading into the mountains and over the Indian border.

These are not easy times to run an irrigation district in California

In February 2006 field tests began on the SonTek® Modbus Interface Module (MIM.) These tests were conducted by the Central Arizona Irrigation District (CAIDD) of Eloy, AZ and the USDA’s U.S. Arid-Land Agricultural Research Center from Maricopa, AZ (formerly the U.S. Water Conservation Laboratory in Phoenix).
