Two modifications, (1) the addition of spatially \nvariable natural recharge from precipitation, and (2) a revised representation of wastewater \nreturn-flow recharge to septic systems in the Town of Barnstable, were made to the \nexisting regional groundwater-flow model for this study. The modified model was \nrecalibrated to the same observations of heads and streamflows as those used in the \noriginal model. The modifications and results of the recalibration are described in the \nappendix of the associated scientific investigations report (https://doi.org/10.3133/sir20195121). \nThe model is a mathematical representation of the groundwater-flow system. Several \nassumptions and limitations of the modeling approach are discussed in the report, as \nwell as in the scientific investigations report describing the original model \n(https://doi.org/10.3133/sir20165058).\n\t\t\nThis USGS data release contains all the input and output files for the simulations described \nin the associated scientific investigations report  (https://doi.org/10.3133/sir20195121).  \nThe modified model supersedes the original model described by Walter and others \n(https://doi.org/10.3133/sir20165058).", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9U5AKLC", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.ff4d786d-0003-4531-b976-1de8b89e9755.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_ff4d786d-0003-4531-b976-1de8b89e9755", "keyword": ["Barnstable", "Bourne", "Brewster", "Cape Cod", "Chatham", "Dennis", "Environment", "Falmouth", "Geoscientific Information", "Groundwater", "Groundwater Model", "Harwich", "Inland Waters", "MODFLOW-2005", "Mashpee", "Massachusetts", "Monomoy lens", "Orleans", "Sagamore lens", "Saltwater Intrusion", "Sandwich", "USGS:ff4d786d-0003-4531-b976-1de8b89e9755", "Yarmouth", "usgsgroundwatermodel"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-70.7254, 41.481709, -69.88939, 41.8655322", "theme": ["geospatial"], "title": "MODFLOW2005 groundwater-flow model used to simulate water-supply pumping scenarios near the Hyannis Ponds Wildlife Management Area, Barnstable, Massachusetts"}
