The previously developed MODFLOW \nmodels (https://doi.org/10.3133/sir20175010 and https://doi.org/10.5066/F73J3B3P) \nwere modified slightly to ensure proper functioning with MODPATH6. Modifications \nto the original MODFLOW models included: 1. changing IPHDRY in the UPW package \nso that the dry cell flag value (HDRY) was written to the binary heads (*.hds) file, 2. \nselecting the compact budget option to ensure proper utilization of IFACE values by \nMODPATH, and 3. the period length (PERLEN) was increased for one model, although \nit has no effect on the simulation.\n\t\t\nThe goal of the modeling exercise was to evaluate the effects of the flow-model (MODFLOW) \nbased complexity on estimates of groundwater age metrics. Results of the evaluation illustrate \nthe importance of properly simulating perennial streams, as both hydraulically fully-penetrating \nstreams and hydraulically partially-penetrating streams influence groundwater ages in aquifers \nby capturing groundwater of differing age that is associated with the aquifer depth from which \nthe groundwater is captured.  This work was performed as part of the National Water Quality \nAssessment (NAWQA) Project's groundwater Mapping and Modeling work plan to evaluate \neffects of differing levels of model complexity on simulated results. This USGS data release \ncontains all of the input and output files for the simulations described in the associated \nGroundwater paper (https://doi.org/10.1111/gwat.13088).\n           ", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P99YKM02", "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.fbf35e7f-ac43-4dac-8087-f1870a663f04.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_fbf35e7f-ac43-4dac-8087-f1870a663f04", "keyword": ["Fox-Wolf-Peshtigo watersheds", "Glacial Aquifer", "Groundwater", "Groundwater Model", "InlandWaters", "MODFLOW-NWT", "MODPATH", "USGS:fbf35e7f-ac43-4dac-8087-f1870a663f04", "Wisconsin", "environment", "geoscientificInformation", "inlandWaters", "usgsgroundwatermodel"], "modified": "2021-03-22T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-90.203574, 43.257882, -87.288050, 46.012123", "theme": ["geospatial"], "title": "MODPATH6 models used to evaluate effects of complexity on groundwater age metrics in the Fox-Wolf-Peshtigo watersheds, Wisconsin"}
