The excel workbook contains: All original data used to support the results and conclusions in the paper, including: Rill transect locations and measurements performed on SfM DEMs, Hillslope and watershed measurements performed on the 1-m LiDAR derived DEM, rill mapping performed on the orthomosaic, volumetric calculations, infiltration data from Kean et al. (2019), infiltration curves, runoff calculations, and the sediment budget for a primary rill on a straight hillslope. The GIS map package contains: Rill transects, rill map shapefiles, 5cm resolution SfM orthomosaics and DEMs, a 30cm orthomosaic (provided by John Warrick at the USGS), geologic contacts, watershed boundaries, infiltration measurement locations, and the flow accumulation grid used for volumetric estimates.


Steps to reproduce

All equations can be found in the supplementary text for the journal article, and the calculations are in the excel workbook. Steps to reproduce rill measurements are found in the methods section of the journal article.
