An existing SEAWAT three-dimensional variable-density groundwater \nflow and transport model (https://doi.org/10.3133/sir20095259) was converted to a MODFLOW\u2013NWT \nthree-dimensional finite-difference groundwater model with the Seawater Intrusion (SWI2) package \nand recalibrated using the UCODE_2005 automatic calibration software. A management goal \nfor the Fire Island National Seashore is to increase the resiliency and capacity of coastal habitat \nand infrastructure to withstand storms and reduce the amount of damage caused by major storms. \nTo facilitate management of ecohydrological effects and to increase understanding of the relation \nbetween sea-level rise and groundwater, as it relates to the ecology of the maritime forests and \nother vegetated areas on the island, the NPS requires hydrologic information. Accelerated sea-level \nrise, storms, rising temperatures, and changes in patterns of precipitation are all expected to \ndrive considerable ecological changes.  This model was used to evaluate three sea-level rise \nscenarios with 0.2-, 0.4-, and 0.6-meter increases above the 2015 level, applied to the existing \ntopography. An additional high-recharge scenario, with the 0.6-meter increase, was created by \nincreasing 2015 recharge rates by 10 percent. Understanding the possible effects of sea-level \nrise and changes in recharge on groundwater resources will allow the NPS to allocate scarce \nresources to best prepare for and manage climate-change-driven changes in the groundwater \nsystem and the subsequent effects on seashore ecosystems. This USGS data release contains \nall of the input and output files for the simulations described in the associated model documentation \nreport (https://doi.org/10.3133/sir20205117).", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P95TBIMW", "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.6ec10aa3-6f43-4fcc-8121-2de42d126e00.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_6ec10aa3-6f43-4fcc-8121-2de42d126e00", "keyword": ["Fire Island", "Groundwater", "Groundwater Model", "InlandWaters", "Long Island", "MODFLOW-NWT", "National Seashore", "New York", "USGS:6ec10aa3-6f43-4fcc-8121-2de42d126e00", "environment", "geoscientificInformation", "inlandWaters", "usgsgroundwatermodel"], "modified": "2021-07-12T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-73.318739, 40.588691 , -72.739250 , 40.785228", "theme": ["geospatial"], "title": "MODFLOW-NWT model used to simulate water-table and freshwater/saltwater interface response to climate-change-driven sea-level rise and changes in recharge at Fire Island National Seashore, New York"}
