ABSTRACT:
The data collected with Acoustic Doppler Current Profiler (ADCP)and Multi-Beam Echosounder (MBES) during a high flow in Mississippi River at Memphis for supporting numerical modeling and testing innovative bedload measurement technologies. These data were processed with a new image-based protocol applied to the acoustic maps collected by MBES and ADCP to proof the performance of a new technique, labelled Acoustic Mapping Velocimetry (AMV). The ADCP data processed with various protocols provided quantification of the bedload geometry and bedload transport rates (via AMV-ADCP technique), suspended sediment in water column (via customized algorithms to process the returned acoustic signal collected along the beams), and the flow hydrodynamics (via ADCP manufacturer processing algorithms).
The ADCP files are provided in customized formats used by the instrument manufacturers. For more information access the instrument manuals at: https://www.teledynemarine.com/brands/rdi/workhorse-sentinel-adcp and https://geo-matching.com/products/geoswath-4r-500-khz for ADCP and MBES, respectively.
