An analytic element GFLOW model was constructed and calibrated to \ngenerate hydraulic boundary conditions for the perimeter of the more detailed \nthree-dimensional MODFLOW-NWT model. This three-dimensional model uses the USGS \nMODFLOW-NWT finite difference code, a standalone version of MODFLOW-2005 that \nincorporates the Newton (NWT) solver. The model conceptualizes the hydrogeology of western \nChippewa County as a six-layer system which includes several hydrostratigraphic units. The \nmodel explicitly simulates groundwater-surface-water interaction with streamflow routing. Model \ninput included recent estimates of aquifer hydraulic conductivities and a spatial groundwater \nrecharge distribution developed using a GIS-based soil-water-balance model for the study \narea. Groundwater withdrawals from pumping were simulated for 269 high-capacity wells \nacross the entire model domain, which includes western Chippewa County and portions of \neastern Dunn County and southeastern Barron County. Model calibration used the parameter \nestimation code PEST, and calibration targets included heads and stream flows. Calibration f\nfocused on the period from during 2011 to 2013 when the largest amount of calibration data \nwere available. Following calibration, the model was applied to two distinct scenarios; one \nevaluating hydraulic impacts of more intensive industrial sand mining and the second evaluating \nthe hydraulicimpacts of more intensive agricultural irrigation practices. Each scenario was \ndeveloped with input by Chippewa County and a stakeholder group established for this study, \nand designed to represent reasonable future build-out conditions for both mining and \nirrigatedagriculture. The mining scenario underscores the potential hydraulic impacts related to \nchanging land-use practices (i.e., hilltops and farm land becoming sand mines), while the \nirrigated agriculture scenario illustrates the potential hydraulic impacts of intensifying existing \nland-use practices (i.e., installing new wells to irrigate farm fields).", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/F7TB15DB", "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.504e59f7-883b-42e9-81fe-4cd4001ce557.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_504e59f7-883b-42e9-81fe-4cd4001ce557", "keyword": ["Chippewa County", "Groundwater", "Groundwater Model", "InlandWaters", "MNW2", "MODFLOW-NWT", "SWB", "USGS:504e59f7-883b-42e9-81fe-4cd4001ce557", "Wisconsin", "environment", "geoscientificInformation", "inlandWaters", "usgsgroundwatermodel"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-91.74356, 44.871185, -91.265762, 45.370969", "theme": ["geospatial"], "title": "MODFLOW-NWT model data sets for simulating effects of groundwater withdrawals on streamflows in Northwestern Chippewa County"}
