maps - Central Valley Hydrologic Model version 2 (CVHM2) simulations of groundwater-level declines for (A) the 2007–2009 drought and (B) the 2012–2016 drought periods. Maps represent simulated groundwater-level differences in the deeper confined system (layer 9 of CVHM2).

map - Land subsidence between June 2015 and April 2023 based on the California Department of Water Resource’s TRE Altamira InSAR Dataset. Also shown are the glaciated and non-glaciated alluvial fans.

maps of model results - Simulated land subsidence in the southern Central Valley (A) from the water year (WY) 1962 to WY 2009. (B) From WY 2000 to WY 2019. (C) From WY 2012 to WY 2016.
