The majority of the data here are the individual photographs used to build the Structure-from-Motion models of the gravel bars used in the study. The photos for each gravel bar are saved in a separate folder. In addition, there are a series of folders which contain the imagery used to produce maps of water surface roughness. There is also tabular data that was generated from the single-beam echo sounder which recorded depth.enCreative Commons BY-NC 4.0-USfluvial geomorphologyhydrologyStructure-from-Motion processgeoreferenced orthophotographsGravel bar analysisparticle size distributionsDataset0000-0002-5450-5763
