Central Valley Hydrologic Model version 2 (CVHM2): Virtual Farm Wells

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2022-10-03T00:00:00Z
This digital dataset contains the location and timing of the virtual farm wells for the updated Central Valley Hydrologic Model (CVHM2). Farm wells are simulated as virtual wells and the screen lengths based on those calculated for the original Central Valley Hydrologic Model (CVHM; Faunt and others, 2009). Farm wells are all simulated as multi-node wells (MNW), which allows for a more realistic distribution of pumping by demand for each water balance subregion. Agricultural Pumping are estimated in CVHM2 by the farm process, and thus are not included in the virtual farm well child item.
