Summary

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 simulated values [...]

Purpose

The Pajaro Valley Hydrologic Model (PVHM) was updated to the latest MODFLOW-OWHM software (Boyce et al., 2020), extended through 2022, and re-calibrated for years 1963-2018. The PVHM was first published model in 2014 (https://pubs.usgs.gov/sir/2014/5111/pdf/sir2014-5111.pdf) and has been used as a tool to evaluate historical changes in groundwater levels and seawater intrusion that have occurred due to anthropogenic pumping in the Pajaro Valley Groundwater Basin, California. This data release archives the updated and extended PVHM with 3 future climate scenarios. The development of the model input and output files included in this data release are documented in the accompanying journal article, “Evaluating Seawater Intrusion Forecast Uncertainty under Climate Change in the Pajaro Valley, California”.
