Data release of Three-Dimensional Hydrogeologic Framework Model of the Petaluma Valley Watershed, Sonoma County, California This digital dataset was created as part of a U.S. Geological Survey study, done in cooperation with the Sonoma County Water Agency and the City of Petaluma, to be used as the digital hydrogeologic input data for numerical simulation of the groundwater system of the Petaluma Valley Watershed, Sonoma County, California. Elevation, thickness, and extent of the hydrostratigraphic units define the geohydrologic layering of the digital framework model. The location of faults may be used to define the location of potential horizontal flow barriers in numerical simulation of the groundwater system. The intended uses of this dataset include, but are not limited to, natural resource modeling, mapping, and visualization applications....

The karstic Edwards and Trinity aquifers that are the subject of the SIM by Clark and others (2020) are classified as major sources of water in south-central Texas by the Texas Water Development Board (George and others, 2011). The geologic framework and hydrostratigraphy of the Edwards and Trinity aquifers largely control groundwater flow paths and storage in northern Medina County...
