Summary

These data were compiled for investigating the relationship between acoustic backscattering by riverbeds composed of various riverbed substrates (bed sediment), and for developing and testing a probabilistic model for substrate classification based on high-frequency multibeam acoustic backscatter. The model is described in Buscombe et al. (2017). The data consist of various quantities on coincident grids, from various sites along the Colorado River in Grand Canyon, including water depth, bed roughness, the area (or footprint) of the acoustic beam, unfiltered and filtered backscatter magnitude, sediment classification (for each location, 1 of 5 sediment classes in a categorical scheme), and the probabilities for each of 5 classes considered [...]

Purpose

Acoustic backscatter data collected by multibeam sonar is used for submerged subtrate classification which is in turn useful for mapping physical habitats and sedimentology of riverbeds. This data include backscatter that has been corrected for the physical roughness of the riverbed. This so-called 'compositional' backscatter is more strongly related to substrate composition and grain size than backscatter that has not been corrected for physical roughness.
