ABSTRACT:

This dataset contains flow and stage data for Rick's Spring, a tributary to the Logan River. The QC0 file contains the raw pressure, temperature, and depth data collected by an in-situ AquaTroll. The QC1 file contains the quality-controlled depth data and the derived stage and discharge data. The depth data is a measure of the water surface elevation relative to the AquaTroll. The derived stage data is the water surface elevation relative to a benchmark at the site. The discharge data is calculated from the stage data using the relationship established from the site rating curve. The stage-discharge relationship was developed by making measurements of flow and stage under varying flow conditions and thus establishing a relationship between water depth and flow at the site. Flow measurements were made with a YSI Flowtracker handheld ADV using the velocity area method.

Red Butte Creek discharge, temperature, and conductivity dataset
Created: July 14, 2016, 10:34 p.m.
Authors: Michelle Barnes · Trinity Stout · Hyrum Tennant · Bethany Neilson

ABSTRACT:

This dataset contains discharge, temperature, and conductivity observations collected longitudinally along Red Butte Creek. Data was collected at approximately 38 sites intermittently dispersed from the Foothill Drive Aquatic Station to the Knowltons Fork Aquatic Station, including tributaries. Periodic data collection began in June of 2014 and continued through the summer of 2015. Measurements were made at each of the sites to capture pre/post snowmelt, summer (high ET) and fall (low ET) conditions. Discharge was measured either using a SonTek Flow Tracker (velocity-area method) or a dilution gaging method (using the YSI 600 OMS and a salt tracer). Temperature and conductivity were measured at each discharge site using the YSI 600 OMS. GPS coordinates for each discharge site were recorded using a Garmin® GPSMAP 64. The purpose for these measurements is to determine areas of significant groundwater-surface water interaction.

Logan River discharge, temperature, conductivity, and chemistry datasets

Authors: Bethany Neilson · Michelle Barnes · Trinity Stout · Hyrum Tennant

ABSTRACT:

This dataset contains discharge, temperature, conductivity, and ion concentration observations collected longitudinally along the Logan River. Data was collected at approximately 38 sites intermittently dispersed from the Mendon Road Aquatic Station to the Tony Grove Aquatic Station, including tributaries. Periodic data collection began in June of 2014 and continued through the summer of 2018. Measurements were made at each of the sites to capture pre/post snowmelt, summer (high ET), fall (low ET), and winter (Low ET) conditions. Discharge was measured using a SonTek Flow Tracker (velocity-area method). Temperature and conductivity were measured at each discharge site using the YSI 600 OMS. Ion samples were immediately filtered using either 0.7 um Whatman GF/F or 0.45 um Whatman Nylon Filters into acid-washed LDPE bottles and frozen (Chloride, Sulfate, Phosphate, Nitrate, Fluoride) or acidified with nitric acid (Sodium, Magnesium, Calcium, Potassium, Ammonium). All samples were transported via cooler to the lab where they were frozen until analysis. Samples were measured by ion chromatography on a Metrohm Compact IC. Standard curves were calibrated using independent NIST-traceable standards, and standards were run as unknowns to check analytical precision. GPS coordinates for each discharge site were recorded using a Garmin® GPSMAP 64. The purpose for these measurements is to determine areas of significant groundwater-surface water interaction.

Authors: Michelle Barnes · Trinity Stout · Hyrum Tennant · Bethany Neilson

ABSTRACT:

This dataset contains discharge, temperature, and conductivity observations collected longitudinally along middle section of the Prove River. Data was collected at approximately 23 sites intermittently dispersed from the Charleston Aquatic Station to the USGS gaging station just below Jordanelle Dam, including tributaries. Periodic data collection began in June of 2014 and continued through August 2014. Measurements were made at each of the sites to capture pre/post snowmelt, summer (high ET) and fall (low ET) conditions. Discharge was measured using a SonTek Flow Tracker (velocity-area method). Temperature and conductivity were measured at each discharge site using the YSI 600 OMS. GPS coordinates for each discharge site were recorded using a Garmin® GPSMAP 64. The purpose for these measurements is to determine areas of significant groundwater-surface water interaction.

ABSTRACT:

Introduction
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

WRR_GIS:
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.

WRR_HEC-RAS:
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.

WRR_GroundTruthing:
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.
