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 Office of Surface Water maintains these web pages to
provide updated information on hydroacoustics instruments and their use
within the USGS and elsewhere.
