A three-dimensional integrated groundwater and surface-water model, GSFLOW, was developed to better understand and manage the groundwater system of the San Antonio Creek Valley watershed, Santa Barbara County, California. The model was calibrated to hydrologic conditions during water years 1948-2018. The model was used to evaluate the interaction between the groundwater and surface-systems and provide average and temporal water budgets for the simulation period. This USGS data release contains all of the input and output files for the simulation described in the associated model documentation report (https://doi.org/10.3133/sir20215139).
Groundwater dependent ecosystems (GDEs) rely on near-surface groundwater. These systems are receiving more attention with rising air temperature, prolonged drought, and where groundwater pumping captures natural groundwater discharge for anthropogenic use. Phreatophyte shrublands, meadows, and riparian areas are GDEs that provide critical habitat for many sensitive species, especially in arid and semi-arid environments. While GDEs are vital for ecosystem services and function, their long-term (i.e. ~ 30 years) spatial and temporal variability is poorly understood with respect to local and regional scale climate, groundwater, and rangeland management. In this work, we compute time series of NDVI derived from sensors...
