SVSim: Sacramento Valley Groundwater-Surface Water Simulation Model

Listed in California Open Data

The Department of Water Resources (DWR) has developed a new model, the Sacramento Valley Groundwater-Surface Water Simulation Model (SVSim).

Description

This new model will support two important DWR programs and has two main goals: 1) Water Transfer Program - develop a tool that meets essential modeling requirements for evaluating project-specific impacts of groundwater substitution transfers on stream depletion in the Sacramento Valley and: 2) Sustainable Groundwater Management Program - develop a tool for evaluating water budgets, surface water-groundwater interactions, and sustainable groundwater management scenarios in the Sacramento Valley.

The intended users of SVSim are DWR, water transfer projects, Groundwater Sustainability Agencies, local agencies, and all other interested parties. SVSim is an application of the Integrated Water Flow Model (IWFM-2015) numerical code and is based on DWR’s C2VSim model (2013). SVSim provides an updated analysis of geologic and hydrogeologic data for the Sacramento Valley and adjacent areas.

The model domain includes the Sacramento Valley Groundwater Basin, the Redding Area Groundwater Basin, and the Delta. The southern model boundary lies between the Mokelumne and Calaveras Rivers. SVSim includes nine (9) layers of variable thickness that span the entire groundwater system.

The base period of the model simulates conditions from 1973 to 2015. A calibrated version of SVSim Version 1.0 is now available. The model input files, output files/data, and the executable program for SVSim Version 1.0 are available for download below.

Version 1.0 supersedes the SVSim Beta Version released in April 2020). Documentation of SVSim model design, input data development, and model calibration and sensitivity analysis is also available.
