Evapotranspiration Units, Groundwater Discharge Area, and 2007-2008 Summer Mean Vegetation Index for Tule Valley and part of Sevier Valley, Utah

This USGS data release consists of three data sets used as the basis for estimates of groundwater discharge from evapotranspiration in Tule Valley and part of Sevier Valley, UT. The data sets are a mapped groundwater discharge area (GDA), a mean modified soil adjusted vegetation index (MSAVI), and evapotranspiration (ET) units derived from the MSAVI within the GDA. The GDA repre

Evapotranspiration Units for Tule Valley and part of Sevier Valley, Utah

This data set represents evapotranspiration (ET) units based on a 2017-2018 summer mean modified soil adjusted vegetation index (MSAVI). The MSAVI information was used to partition Tule Valley and part of Sevier Valley, UT into six discharging ET units (playa; open water; very sparse desert shrub; sparse-to-dense desert shrub; grassland; and dense meadow and marshland),

Groundwater Discharge Area for Tule Valley and part of Sevier Valley, Utah

The groundwater discharge area (GDA) in Tule and part of Sevier valley represents the area where discharge from evaporation by open water or bare soil and transpiration from phreatophytic plants exceeds the volume of water contributed by precipitation. The GDA was delineated during field reconnaissance of the study area using techniques similar to those used in previous studies throughout Nev...

Scaled Modified Soil Adjusted Vegetation Index for Tule Valley and part of Sevier Valley, Utah

The mean MSAVI image is based on two Landsat 5 Thematic Mapper (TM) scenes representing midsummer conditions in 2007 and 2008. MSAVI was calculated for each image which were then combined by calculating the mean for each pixel in the scenes. The resultant MSAVI image was used to estimate vegetation assemblages (ET units) within a mapped groundwater discharge area.

Lumped parameter models of groundwater age from the Columbia Plateau Aquifer, Vertical Flowpath Study Network

This data release documents two Microsoft Excel tables that contain data for understanding tracer concentrations and groundwater age in the Columbia Plateau aquifer system. Results for geochemical correction of carbon-14, and lumped parameter modeling of groundwater age for the sample network (VPFS, vertical flow path study) are described. Geochemical carbon-14 correction results (RFG

Lumped parameter models of groundwater age, Spanish Valley Watershed, Grand and San Juan Counties, Utah

This data release documents two Microsoft Excel tables; one contains data for understanding groundwater ages in the Spanish Valley watershed, and one that describe the data fields. Mean ages and age distributions from 19 groundwater samples were estimated in support of an evaluation of the groundwater resources of the Spanish Valley watershed (Masbruch and others, 2019). Individual gro

SPARROW model inputs and simulated streamflow, nutrient and suspended-sediment loads in streams of the Southwestern United States, 2012 Base Year

The U.S. Geological Survey's (USGS) SPAtially Referenced Regression On Watershed attributes (SPARROW) model was used to aid in the interpretation of monitoring data and simulate streamflow and water-quality conditions in streams across the Southwestern Region of the Unites States. SPARROW is a hybrid empirical/process-based mass balance model that can be used to estimate the major sou
