Upper Midwest Water Science Center uses acoustic meters for making streamflow measurements. Wading measurements are done using a modified top setting wading rod equipped with an acoustic Doppler velocimeter (ADV). Acoustic Doppler current profilers (ADCP) are used when measurement depths are too deep to wade. ADCP measurements can either be made with a tether or cableway or deployed on a manned boat. Streamflow in nine locations where backwater or other conditions preclude the use of a conventional stage-discharge rating are measured using fixed acoustic Doppler velocity meters (ADVM) mounted both horizontal and vertical to the principal flow direction. Acoustic instrumentation has also been used to map cross-sectional and longitudinal areas for studies of critical Asian carp habitat in the St. Joseph, Maumee, and Sandusky Rivers and in conjunction with research following the oil spill in 2011 on the Kalamazoo River.
