Regional Groundwater-Withdrawal Studies
The USGS, in cooperation with DOE, developed a transient groundwater flow model to evaluate the effects of NNSS activities on the regional groundwater flow system (Belcher and Sweetkind, 2010). A spatially and temporally distributed database of anthropogenic groundwater withdrawals was developed in support of the groundwater flow model (Moreo and others, 2003). This database documents regional groundwater withdrawals from 1913 to 1998. Withdrawal estimates were refined and updated through 2003 as part of a continuing effort to improve and update the groundwater flow model (Moreo and Justet, 2008).
