Potential areas of groundwater discharge, Humboldt River Basin, Nevada

Potential areas of groundwater discharge were delineated for the Humboldt
River Basin to estimate groundwater evapotranspiration from phreatophyte
vegetation, the primary component of natural groundwater discharge in the
region. The boundary that defines the potential area of groundwater
discharge represents the maximum spatial extent of groundwater discharge
by phreatophyte vegetation, and areas within this boundary may discharge
little to no groundwater where bare soil or sparse vegetation is the
primary land cover. The boundaries are based on the original delineations
of phreatophyte vegetation published in Reconnaissance Series Reports and
Water Resource Bulletins for the state, which have also been included in
this database with the filename
"Historical_recon_and_wrb_phreatophyte_boundaries.shp".
