In analytic-element models significant streams and \nlakes in the model domain are represented as linesink elements. Analytic-element models, \nsuch as the SLRB regional model, can be a screening model which provides a simplified version \nof a hydrologic system, completed ahead of a more complex modeling effort. For this study, \nthe regional screening model was refined to focus on extensive ditching in the central SLRB, \na wetland-rich area to the south of the Iron Range.  Two smaller models were developed in this \narea\u2014a ditch model and a pre-ditch model.  The effect of ditching was evaluated by comparing \ntwo separate model runs, one with the ditch network represented as linesinks and a \u201cpre-ditching\u201d \nmodel with ditch linesinks removed.  Additional calibration of the ditch scenario models was done \nto improve modeled groundwater levels in the wetlands. This USGS data release contains all of \nthe input and output to run the model simulations described in the associated model documentation \nreport (https://doi.org/10.3133/sir20195033).", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9KUJ0L3", "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.0f29e8cd-8b3a-426f-bc3f-39fcc989eecc.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_0f29e8cd-8b3a-426f-bc3f-39fcc989eecc", "keyword": ["GFLOW", "Groundwater", "Groundwater Model", "InlandWaters", "Itasca County", "Lake County", "Mesabi Range", "Minnesota", "PEST", "Soil-Water-Balance Code", "St. Louis County", "USGS:0f29e8cd-8b3a-426f-bc3f-39fcc989eecc", "environment", "geoscientificInformation", "inlandWaters", "usgsgroundwatermodel"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-93.458137, 46.524454, -91.109073, 48.120011", "theme": ["geospatial"], "title": "GFLOW groundwater flow model of the St. Louis River Basin, Minnesota"}
