OSW Hydroacoustics

These pages provide information on hydroacoustic technology for users in the USGS and other agencies. Since the early 1980s the USGS has worked cooperatively with manufacturers to develop and enhance the use of acoustic Doppler instruments for streamflow and other hydraulic measurements. The Hydroacoustics Workgroup and the Hydrologic Networks Branch maintains these web pages to provide updated information on hydroacoustics instruments and their use within the USGS and elsewhere.


What's New?

New Software/Firmware for SonTek SL

The USGS has worked cooperatively with SonTek to improve the SL3G software and firmware. Vesion 3 was release on 6/6/2018 and is now the recommended version. See the list of changes and improvements on the SonTek-SL Software Page.

New Version of VMT

A new version of VMT was released on 7/15/2018. To see the list of changes and improvements and to download the software go to the VMT Software Page. Note: For USGS System Administrators VMT is available via SCCM.

DCP Script Repository!

Configuring a DCP to communicate with an ADVM and log all the desired variables can be confusing and time consuming. The HaWG has created a repository where field personnel can share scripts they have used to configure DCPs to communicate and log ADVM data. Please share your scripts and search the repository before writing a new script to see if that problem has already been solved. Note: While the primary focus is on scripts supporting ADVM use, you are encouraged to share any script you think would be useful to others.
