MODFLOW2000_FMP1_1 model used to simulate the groundwater flow of the Central Valley Aquifer, California
Description
A three-dimensional groundwater flow model (MODFLOW200-FMP1_1) of the Central Valley in
California was developed to aid water managers in understanding how water moves through the
aquifer system, to predict water-supply scenarios, and to address issues related to water
competition. The USGS Groundwater Resources Program made a detailed assessment of
groundwater availability of the Central Valley aquifer system, which includes:
(1) the present status of groundwater resources;
(2) how these resources have changed over time; and
(3) tools to assess system responses to stresses from future human uses and climate
variability and change. This effort builds on previous investigations, such as the USGS
Central Valley Regional Aquifer System and Analysis (CV-RASA) project and several
other groundwater studies in the Valley completed by Federal, State and local agencies
at differing scales. The principal product of this new assessment is a tool referred to as
the Central Valley Hydrologic Model (CVHM) that accounts for integrated, variable water
supply and demand, and simulates surface-water and groundwater-flow across the entire
Central Valley system. The current model was extended to incorporate a slightly larger
geographic area, has a finer spatial and temporal discretization, uses a more-detailed
depiction of subsurface geology. In addition, the model utilizes a modified version of
MODFLOW2000 (version 1.15.03) to include an updated and refined Farm Process (FMP1)
to simulate groundwater and surface-water flow, irrigated agriculture, land subsidence, and
other key processes in the Central Valley on a monthly basis for April 1961 through
September 2003. This USGS data release contains all of the input and output files for
the simulation and calibration of the CVHM described in the associated model
documentation report (https://pubs.er.usgs.gov/publication/pp1766).
