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.
