Climate change and climate variability impacts such as rising sea levels have the potential to exacerbate seawater intrusion and the strain on coastal freshwater resources in already stressed groundwater basins such as those in the Pajaro Valley groundwater basin, California. The U.S. Geological Survey (USGS) developed the Pajaro Valley Hydrologic model (PVHM) to quantitatively assess aquifer-system responses to climatic variation, surface-water deliveries, and seawater intrusion.The PVHM historical model (1963-2018) was updated, extended, and re-calibrated using a combination of manual adjustments to parameters and an assisted parameter estimation PEST++ software (White et al., 2020) to minimize differences between...
