Subsurface model Petaluma, Sonoma County, CA

3D Model

Vertical cross sections cut through three-dimensional hydrogeologic framework model of the Petaluma Valley Watershed, Sonoma County, California. This model was constructed to define the aquifer system geometry and subsurface lithologic characteristics and distribution for use in a regional numerical hydrologic model.

The 3D model is described and documented in USGS report: https://doi.org/10.3133/sir20225009 3D model digital data are archived in USGS Data Release: https://doi.org/10.5066/P9NL90P8
