Central Valley Hydrologic Model version 2 (CVHM2): Well Log Database
This data release provides updated borehole information to build upon and further refine a three-dimensional (3-D) texture model of valley-fill deposits in the Central Valley created by Faunt and others (2009). This model aids in understanding the aquifer system of the entire valley and will be later utilized in a groundwater flow model. The original database contained approximately 8,500 boreholes and with the addition of new data, the model now contains 14,683 boreholes. The new borehole lithologic data was sourced from the California Department of Water Resources (DWR) Online System of Well Completion Reports (OSWCR) and the California Central Valley Groundwater-Surface Water Simulation Model (C2VSim). This dataset contains (1) tabular data of individual borehole general location and construction information, (2) downhole lithologic interval data derived from well driller’s lithology logs and parsed to a series of textural descriptors.
