Summer Mean Enhanced Vegetation Index for the Diamond Valley Flow System Groundwater Discharge Area, Central Nevada, 2010
Description
These data were created as part of a hydrologic study to characterize groundwater budgets and water quality
in the Diamond Valley Flow System (DVFS), central Nevada. This dataset represents the mean Enhanced
Vegetation Index (EVI) of two Landsat 5 Thematic Mapper scenes from the summer of 2010 in the DVFS.
The data were used to evaluate and estimate groundwater discharge by evapotranspiration by relating the
mean of EVI calculated from July 24 and August 25, 2010 Landsat scenes to evapotranspiration measured
at 4 eddy-covariance sites located in phreatophytic vegetation of varying types and densities in Kobeh Valley,
Nevada. Evapotranspiration was extrapolated for all valleys in the study area using the relation developed
for Kobeh valley.
