The model was constructed using existing \nhydrogeologic and geospatial information to represent the aquifer system geometry, boundaries, and \nhydraulic properties of the 19 separate regional aquifers and confining units within the aquifer system.  \nThe model was calibrated using an inverse modeling parameter-estimation (PEST) technique to conditions \nfrom 1986 to 2008, the period for which data are most complete and reliable.  The simulation period for this \nanalysis spanned from predevelopment to future conditions, from 1900 to 2058. The model was used to \nadvance the understanding of groundwater budgets and components including recharge, discharge, and \naquifer storage for the entire system and for each of the statewide systems; compute historical and recent \nsystem response and project future system response to development at a scale relevant to basinwide \nwater-management decisions; and evaluate options for hydrologic monitoring of system changes.
