The three-dimensional, steady-state groundwater-flow model used to simulate water level changes is a modified and recalibrated version of an existing model that was used to simulate the potential effects of sea-level rise on groundwater levels of the Sagamore and Monomoy freshwater lenses of the Cape Cod aquifer (Walter and others, 2016) (https://doi.org/10.3133/sir20165058). Two modifications, (1) the addition of spatially variable natural recharge from precipitation, and (2) a revised representation of wastewater return-flow recharge to septic systems in the Town of Barnstable, were made to the existing regional groundwater-flow model for this study. The modified model was recalibrated to the same observations of heads and streamflows as those used in the original model. The modifications and results of the recalibration are described in the appendix section of the model documentation report (https://doi.org/10.3133/sir20195121). The model is a mathematical representation of the groundwater-flow system. Several assumptions and limitations of the modeling approach are discussed in the report, as well as the scientific investigations report describing the original model(https://doi.org/10.3133/sir20165058). This USGS data release contains all of the input and output files for the simulations described in the associated model documentation report (https://doi.org/10.3133/sir20195121). The modified model supersedes the original model described by Walter and others (https://doi.org/10.3133/sir20165058). The directories described below contain all the input and output files for the simulations of the nine pumping scenarios described in the associated scientific investigations report, including the MODFLOW-2005 source code. The data release also contains all the input and output files for two simulations of areas of fine-grained sediments and 87 simulations of a single well at various locations. Descriptions of the data in each subdirectory are provided to facilitate understanding of this data release. Additional descriptions are provided for selected files to provide information that may be of use when working with this model archive. Hydrologic simulations were run with MODFLOW-2005 (v. 1.11.00). No modifications were made to this code. Support is provided for correcting errors in the data release and clarification of the modeling conducted by the U.S. Geological Survey. Users are encouraged to review the documentation of the model in the associated scientific investigations reports (https://doi.org/10.3133/sir20165058 and https://doi.org/10.3133/sir20195121) to understand the purpose, construction, and limitations of this model. Reconstructing the data release from the online data release: ------------------------------------------------------------- This data release is available from: https://doi.org/10.5066/P9U5AKLC The models will run successfully only if the original directory structure is correctly restored. The data release is divided into several sections to reduce the likelihood of download timeouts. Small files (readme.txt and modelgeoref.txt) are available as uncompressed files. All other files are zipped at the subdirectory level. For example, the files in the "georef" subdirectory are zipped into a zip file named "georef.zip". All zip files should be unzipped into a directory with the same name as the zip file name without the .zip extension. Please create a model folder on your computer and place the zipped compressed files starting with "/model/" in the download pathname in a "/model/" subdirectory. Example: /sir2019-5121/model/externalfiles.zip. Also, create an output folder on your computer and place the zipped compressed files starting with "/output/" in the download pathname in a "/output/" subdirectory. Example: /sir2019-5121/output/output.calibrated.zip The highest-level directory structure of the original data release is: SIR2019-5121/ ancillary/ bin/ georef/ model/ output/ source/ The full directory structure of the data release and the zip files associated with each subdirectory are listed below. System requirements: -------------------- The models contained in this data release were run using the mf2005.exe executable in the bin zip file in this data release.
