A previously developed three-dimensional steady-state numerical groundwater-flow model was modified to transient conditions with respect to well withdrawals, and used to simulate drawdown and capture of natural discharge from existing and proposed groundwater withdrawals in Snake Valley and adjacent areas in western Utah and eastern Nevada. The original steady-state model simulates and was calibrated to 2009 conditions and was used as the first stress period in this transient model. Six transient stress periods, spanning 2010-2114, were added to the model to assess timing of the potential withdrawal effects. A seventh steady-state stress period was also added to determine the ultimate long-term effects of the well...

A previously developed numerical groundwater flow model of the eastern Great Basin was used to investigate where potential drawdown and capture of natural discharge is likely to result from potential groundwater withdrawals from existing and applied for groundwater rights in Snake Valley, Utah and Nevada. SIR 2014-5213 (https://doi.org/10.3133/sir20145213), SIR 2017–5011 (https://doi.org/10.3133/sir20175011), and SIR 2017-5072 (https://doi.org/10.3133/sir20175072) document the construction and calibration of the previous versions of this model. The eastern Great Basin model consists of a parent model and a child model. The parent model covers the focus study area and was used for the simulations presented in this...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
