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.

README - Memphis ADCP and MBES Datasets
This README provides an overview of the data files contained in the following two datasets:
1. ADCP Dataset: ADPC_Memphis USGS 362022_0
Location:
Files prefixed with memphis in the ADPC_Memphis USGS 362022_0 directory.
Description:
These files represent Acoustic Doppler Current Profiler (ADCP) data collected by the USGS at the Memphis site (Station ID: 362022_0). The dataset includes:
- .PD0 files containing raw ADCP velocity and backscatter profiles.
- .MMT files likely representing metadata or instrument deployment configuration.
These datasets are used to analyze river flow velocities, discharge, and related hydrodynamic properties.
2. MBES Dataset: MBES_Processed
Location:
Subdirectories s1 through s11 inside the MBES_Processed directory.
Description:
Each subfolder (e.g., s1, s2, ..., s11) contains processed multibeam echosounder (MBES) data in .xyz format. These represent high-resolution bathymetric measurements collected from different spatial partitions of the surveyed area.
Each .xyz file typically includes:
- X: Easting or Longitude
- Y: Northing or Latitude
- Z: Depth or Elevation (usually in meters)
This data supports riverbed morphology studies, sediment transport modeling, and flood risk assessments.
Notes
- Ensure the coordinate system and units are validated before analysis.
- ADCP and MBES datasets may be combined for integrated hydrodynamic and morphologic assessments.
