Masbruch", "hasEmail": "mailto:mmasbruch@usgs.gov"}, "description": "A three-dimensional groundwater flow model, MODFLOW-NWT, was developed to simulate saturated groundwater hydrology, streamflow, and groundwater/surface-water interaction within the Colorado Plateau principal aquifer system. The model was used to evaluate and compare the hydrologic responses of groundwater and streamflow to natural and anthropogenic drivers of change between a recent wet period (1982-1999) and drought period (2000-2022) for four headwater subregions in the Upper Colorado River Basin.
