USGS Hydroacoustics Work Group

The Hydroacoustic Work Group (HaWG) provides guidance to the Water Mission Area (WMA) regarding the support for and development of hydroacoustics instrumentation for use in streamflow, velocity, depth, and other hydraulic and hydrologic measurements. This guidance often takes the form of advice regarding technical issues that need to be addressed, work priorities, and funding for hydroacoustics within the WMA. The HaWG also facilitates communication between WMA and hydroacoustics users. It has rotational, permanent, ad hoc, and cooperating agency members. The rotational members serve 5-year terms.
