BARCAS - Basin and Range Regional Carbonate-rock Aquifer System

Affiliation(s)PIProject periodFunded by
DHS Jim Thomas

Project Description

The BARCAS study was conducted to assess the water resources of the alluvial and carbonate aquifers in White Pine County, Nevada, and surrounding areas. As a part of this study, reports describing (1) the water quality in the BARCAS study area, recharge altitudes, groundwater flow paths and groundwater residence time; (2) chloride mass balance recharge estimates; (3) DSC models that account for groundwater recharge, discharge, and inter- and intra-basin flow; (4) uncertainty analysis of groundwater discharge estimates; (5) methods for mapping desert shrubs in groundwater discharge areas; (6) assessment of evapotranspiration mapping units; and (7) comparison of evapotranspiration rates from phreatophytic vegetation using different eddy correlation techniques.
