    dct:description "The U.S. Geological Survey obtained measurements of channel geometry, flow velocity, and river discharge from five rivers in Alaska September 18-20, 2016, to support research on remote sensing of river discharge.  The streamflow data were acquired from the Knik, Matanuska, Chena, and Salcha Rivers and Montana Creek using TeleDyne RD Acoustic Doppler Current Profilers (ADCPs), including the RioPro, StreamPro, and RiverRay models.  The original *.mmt and *.pd0 format files are provided in this data release." ;
