Multibeam echosounders (MBES) collect multibeam and sidescan simultaneously, providing high-resolution images of the riverbed. Sidescan images, in raster format, show the recorded intensity of acoustic signal returns from the riverbed. The acoustic data were collected from the main and side channels (where accessible) of the Dresden reach June 4 – 28, 2018.

Small areas containing priority mussel habitat had additional collection efforts to map water velocities and bottom composition. Combining these data in a GIS can provide key components to characterizing physical benthic habitat for native mussels in a riverine environment. These information needs were highly desired by the National Park Service to more accurately assess environmental factors that influence native mussel distribution. The collaborative effort was funded by the Legislative-Citizen Commission on Minnesota Resources (LCCMR) Environment...

Backscatter is the acoustic reflectivity, which is the measure of energy obtained from the echo intensity, and can provide an indication about the nature of the river bottom and its physical character. Image analysis and classification of backscatter, with the combined datasets of bathymetry (and its derivatives) and ground truthing, can predict surficial substrate, or sediment type. For habitat analysis, these datasets were desired by the NPS to help inform and mitigate...
