    dct:description """The previously developed three-dimensional groundwater flow model (MODFLOW2000) of the Denver Basin 
bedrock aquifer system and overlying alluvial aquifer (https://pubs.er.usgs.gov/publication/pp1770 and 
model archive https://doi.org/10.5066/F77W69PQ) was updated to provide quantitative estimates of 
groundwater flow conditions and provide a useful tool for managers to analyze temporal changes to the 
hydrologic system in response to changing climatic conditions and future groundwater development. The 
computer program ZONEBUDGET was used to calculate cell by cell water balances for the major 
components of the water budget for the Upper Big Sandy Designated Groundwater Basin alluvial aquifer. 
The original Denver Basin groundwater flow model was done as part of a large-scale regional groundwater 
availability study of the principal aquifers and represents regional time-varying (transient) conditions prior 
to 1880 through 2003. This model was updated to include updated well pumping data through 2016.  This 
U.S. Geological Survey data release contains all of the input and output files for the simulation described 
in the associated model documentation report (https://doi.org/10.3133/sir20195049).""" ;
