A three-dimensional groundwater flow model was developed in 1997 to evaluate the groundwater flow system at Puget Sound Naval Shipyard, Naval Base Kitsap, Bremerton, Washington (https://pubs.er.usgs.gov/publication/wri964147). In 2016, a regional groundwater flow model for the greater Kitsap Peninsula was developed (https://pubs.er.usgs.gov/publication/sir20165052). Using information from the 2016 regional model, the 1997 groundwater flow model for the Puget Sound Naval Shipyard was updated with a new interpretation of the underlying hydrogeologic units, a refined model grid, and improved recharge estimates. A steady-state model version was constructed in MODFLOW-NWT to simulate equilibrium conditions. MODPATH forward...

A three-dimensional groundwater flow model, constructed in MODFLOW-NWT, was developed to evaluate the groundwater flow system near Puget Sound, Pierce and King Counties, Washington. A steady-state model version was constructed to simulate equilibrium conditions, while a transient model version was constructed to simulate monthly variability from January 2005 to December 2015. The model was used to simulate several hydrologic scenarios. This data release contains the input and output files for the simulations described in the associated model documentation report (https://doi.org/10.3133/sir20245026v2).

Head-observation files to identify the highest simulated water table for Clover Creek watershed, Pierce County, Washington

The depths to a high and average water table below the land surface were estimated across the Clover Creek watershed in Pierce County, Washington. Groundwater model simulations provided initial estimates of water-table depths for the analysis. To provide optimized, data-driven estimates of these depths, a continuous bias correction surface was applied to model output according to differences between simulated and observed water levels at observation wells.

This data release consists of the initial well input data for the logistic regression model, the conceptual well data for logistic mapping, the logistic mapping output data, the logistic mapping output vulnerability and vulnerability difference rasters, and supporting geographic information system (GIS) files for the study titled "Index of Vulnerability for Elevated Nitrates in Groundwater in the Puget Sound, Washington."
