Overview
DWR’s California Central Valley Groundwater-Surface Water Simulation Model, C2VSim, simulates the monthly response of the Central Valley’s groundwater and surface water flow system to historical stresses, and can also be used to simulate
the response to projected future stresses. C2VSim contains monthly historical stream inflows, surface water diversions,
precipitation, land use and crop acreages from October 1921 through September 2009. The model dynamically calculates
crop water demands, allocates contributions from precipitation, soil moisture and surface water diversions, and calculates the groundwater pumpage required to meet the remaining demand.
C2VSim is run with DWR’s Integrated Water Flow Model (IWFM) program. Software tools distributed with C2VSim allow
users to import and review water budgets in MS Excel, create movies of groundwater heads and subsidence with
TecPlot®, and view a wide variety of results in ArcMap. C2VSim can also be used in water resources planning, including
integrated regional management planning, climate change assessments, understanding stream-groundwater interactions, and groundwater storage investigations.
The workshop will provide an introduction to the historical evolution of the Central Valley’s water resources system as
encapsulated in C2VSim. The hands-on portion of the workshop will train new users on how to run the C2VSim model, analyze simulation results and prepare scenarios.
Workshop participants will need to bring a laptop computer with MS Windows and several programs installed, including ESRI ArcMap, MS Excel, and a programming text editor
such as TextPad or MultiEdit. Before the workshop, participants will need to download and install the C2VSim model, C2VSim ArcMap GUI Tool and C2VSim ArcMap GUI files, available from the DWR C2VSim web site, and the IWFM Tools Add-In for Excel.
Major topics will include:
- Overview of Central Valley hydrology
- How the Central Valley hydrologic system is represented in C2VSim
- Explanation of the land surface, surface water and groundwater budgets for the 1922-2009 historical simulation
- Mechanics of running C2VSim (IWFM Preprocessor, Simulation, Budget and Z-Budget programs)
- Input files for C2VSim
- Post-processing C2VSim results
- Using TecPlot® to create a movie of groundwater heads
- Using ArcMap to display results
- Developing a case study for a groundwater pumping project and an aquifer storage and recovery project
