This document provides an overview of the accompanying data files used in the production the accompanying manuscript. 
Text S1.
For each virtual gauging station, we have included:
1. NIR orthorectified mosaics for each flight
2. Low flow RGB orthorectified mosaic and DSMs
3. Shapefiles of the hydraulic model domains
4. HEC-RAS models
5. Total station channel surveys
6. In situ observations of wetted width and wetted widths extracted from imagery

All of the imagery, digital surface models, and shapefiles for the hydraulic model domains (items 1-3 above) are included in the WRR_GIS folder. To view these data, launch the included ArcMap Map Document: KingEtAl_WRR_2017.mxd. Data reference paths are relative for inter computer fidelity. This map document was produced with ArcMap 10.3. The hydraulic domain shapefile data were used to produce the geometry files used in HEC-RAS with the HEC-GeoRAS toolkit.

The HEC-RAS models (item 4 above), produced in HEC-RAS 5.0.3 are provided in the folder WRR_HEC-RAS. The project files for each virtual gauging station are located in WRR_HEC-RAS \ VGS# \ Projects where VGS# is virtual gauging station number of interest. These project files contain the information to run the open channel hydraulic models. Opening these files will prompt a warning message that some files were not found. These files were test runs that are not germane to the final results and were therefore not included in an attempt to minimize confusion. Note that HEC-RAS models follow our local naming convention and map onto the virtual gauging station naming convention as follows: VGS1 = Kup8US, VGS2 = Kup7DS, VGS3 = Kup5uus.

The ground truthing data (items 5 and 6 above) are included in csv files within the WRR_GroundTruthing folder. Total station surveys are provided along with corresponding elevations extracted from the Digital Surface Models in csv files located at WRR_GroundTruthing \ ChannelSurveys \ VGS#TransectCompare.csv where VGS# is the virtual gauging station of interest. Observed wetted width and the corresponding wetted widths extracted from the NIR mosaics are provided in the csv file: WRR_GroundTruthing \ WettedWidths \ WettedWidthComparison.csv.
