Description

The excel workbook contains: All original data and calculations 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, data collected in artificial rainfall experiments on steep short plots by Wu et al. (2017), Zhang et al. (2017), and Zhang et al. (2019) for RIFT estimates, data from laboratory experiments performed by Lei et al. (2002 a,b), Chen et al. (2014), and Jiang et al. (2018a) used in calculating rates of bed erosion and sediment transport in rills, and calculations of rill flow for different widening and deepening scenarios. 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.
