Steve has worked in groundwater hydrology and flow modeling for over 20 years, mainly on the High Plains of Nebraska. At the USGS Nebraska Water Science Center, Steve incorporates the latest groundwater and integrated modeling approaches to provide comprehensive information for science-based water resources management at local, state, and federal levels. Steve has recently completed the High Plains Groundwater Availability Study, assessing the processes and current and future status of the water resources of the High Plains aquifer, a region sustaining approximately one-quarter of the Nation’s agricultural production through groundwater irrigation. Steve’s other local or regional modeling studies include depletion mapping, optimization modeling, soil-water balance modeling, landscape hydrology modeling, parallel computing for parameter estimation and collaboration on integration of geophysical and geologic data in groundwater models.
