Joint Base Cape Cod (JBCC) Installation Restoration Program (IRP) Regional Groundwater Model

This resource contains the input files for the JBCC regional model, which is a 378 row, 293 column, and 40 layer MODFLOW 2000 model. Included are the formation file and lens topography files used to build both the regional model and the well file.

This regional model of JBCC was updated/recalibrated in 2005 and is documented in Appendix C of the \"Final Chemical Spill-23 (CS-23) Wellfield Design Report\". This document is available on the AF administrative record as AFCEC document number 18387 at https://ar.afcec-cloud.af.mil/.

Also attached to this resource are figures showing the regional model extent (C-1), the model grid configuration (C-21), and the model-predicted groundwater contours (C-22).

There are also 12 site specific models for each of the groundwater plumes that are within the domain of this larger regional model.
