Replication Data for: Southard, P. J., Johnson, J. P. L., Rempe, D. M., & Matheny, A. M. (2022). Impacts of vegetation on dryland river morphology: Insights from spring-fed channel reaches, Henry Mountains, Utah. Water Resources Research, 58, e2021WR031701. https://doi.org/10.1029/2021WR031701

This dataset contains five zipped folders of files (zipped using the built-in function in Windows 10 Pro). DSW is the downstream Woodruff Canyon reach, TRL is the Trail Canyon reach, and USW is upstream Woodruff Canyon reach. Each folder contains a README.txt file that gives information for interpreting the data (especially useful for the "Pickled" python data for channel geometry).

In the "Model_Results" folder, models ending in "_r" describe the variable roughness model runs (the other folders and subfolders are the uniform hydraulic roughness runs (Manning's n=0.04). Data on modeled flow depth, velocity, and momentum are provided as TIF images with associated world files and projection information. "fbe" (in each filename) indicates that the model was run on the "filled bare earth elevation" topography (every model was run using this topography).

The "Processed_LiDAR_Data" folder contains TIFs of topography (fbe) and also of LVI (our LiDAR vegetation index). "Tabular_Data" contains xlsx spreadsheets for cross section-averaged discharge and related flow modeling data, and also tables of statistical fits. The "Xsections_wetted" folder contains png images of plots approximating channel cross sections. In particular and as also stated in the README.txt file, these cross sections will be close to the measured topography, but not exact, because these were calculated assuming a flat water surface, even though AnUga allows variations in water surface elevation to develop. This is just based on how we pulled the data initially (relative to water surface at a given location, rather than pulling topography across the cross section and water surface elevation separately).
