Philip Gardner
Philip Gardner is a Hydrologist and the Groundwater Specialist for the Nevada Water Science Center.
Phil has worked as a hydrologist with the US Geological Survey since 2001 and is currently the Groundwater Specialist at the Nevada Water Science Center in Carson City, NV. Much of his work has focused on the development of conceptual and numerical models of hydrologic systems and groundwater-surface water interaction throughout the eastern Great Basin and Colorado Plateau.

Electrical Geophysical Data Collected in the Scott M. Matheson Wetlands Preserve Near Moab, Utah Electrical Geophysical Data Collected in the Scott M. Matheson Wetlands Preserve Near Moab, Utah
Quantitative evaluation of groundwater/surface water exchange dynamics is universally challenging in large river systems, because existing physical methodology often does not yield spatially-distributed data and is difficult to utilize in deeper water. Here we apply combined frequency domain electromagnetic induction (EMI) and direct contact vertical electrical sounding (VES)...

Wetland-scale mapping of preferential fresh groundwater discharge to the Colorado River Wetland-scale mapping of preferential fresh groundwater discharge to the Colorado River
Quantitative evaluation of groundwater/surface water exchange dynamics is universally challenging in large river systems, because existing methodology often does not yield spatially‐distributed data and is difficult to apply in deeper water. Here we apply a combined near‐surface geophysical and direct groundwater chemical toolkit to refine fresh groundwater discharge estimates to the...

Effects of groundwater withdrawals from the Hurricane Fault zone on discharge of saline water from Pah Tempe Springs, Washington County, Utah Effects of groundwater withdrawals from the Hurricane Fault zone on discharge of saline water from Pah Tempe Springs, Washington County, Utah
Pah Tempe Springs, located in Washington County, Utah, contribute about 95,000 tons of dissolved solids annually along a 1,500-foot gaining reach of the Virgin River. The river gains more than 10 cubic feet per second along the reach as thermal, saline springwater discharges from dozens of orifices located along the riverbed and above the river on both banks. The spring complex...

Evaluating micrometeorological estimates of groundwater discharge from Great Basin desert playas Evaluating micrometeorological estimates of groundwater discharge from Great Basin desert playas
Groundwater availability studies in the arid southwestern United States traditionally have assumed that groundwater discharge by evapotranspiration (ETg) from desert playas is a significant component of the groundwater budget. However, desert playa ETg rates are poorly constrained by Bowen Ratio energy budget (BREB) and eddy-covariance (EC) micrometeorological measurement approaches...

Hydrogeologic and geochemical characterization of groundwater resources in Deep Creek Valley and adjacent areas, Juab and Tooele Counties, Utah, and Elko and White Pine Counties, Nevada Hydrogeologic and geochemical characterization of groundwater resources in Deep Creek Valley and adjacent areas, Juab and Tooele Counties, Utah, and Elko and White Pine Counties, Nevada
The water resources of Deep Creek Valley were assessed during 2012–13 with an emphasis on better understanding the groundwater flow system and groundwater budget. Surface-water resources are limited in Deep Creek Valley and are generally used for agriculture. Groundwater is the predominant water source for most other uses and to supplement irrigation. Most groundwater withdrawal in Deep...

A multiple-tracer approach to understanding regional groundwaterflow in the Snake Valley area of the eastern Great Basin, USA A multiple-tracer approach to understanding regional groundwaterflow in the Snake Valley area of the eastern Great Basin, USA
Groundwater in Snake Valley and surrounding basins in the eastern Great Basin province of the western United States is being targeted for large-scale groundwater extraction and export. Concern about declining groundwater levels and spring flows in western Utah as a result of the proposed groundwater withdrawals has led to efforts that have improved the understanding of this regional...

Potential effects of existing and proposed groundwater withdrawals on water levels and natural groundwater discharge in Snake Valley, Juab and Millard Counties, Utah, White Pine County, Nevada, and surrounding areas in Utah and Nevada Potential effects of existing and proposed groundwater withdrawals on water levels and natural groundwater discharge in Snake Valley, Juab and Millard Counties, Utah, White Pine County, Nevada, and surrounding areas in Utah and Nevada
Applications have been filed for several water-right changes and new water rights, with total withdrawals of about 1,800 acre-feet per year, in Snake Valley near Eskdale and Partoun, Utah. The Bureau of Land Management has identified 11 sites where the Bureau of Land Management holds water rights and 7 other springs of interest that could be affected by these proposed groundwater...
