Research Interests:

Steven P. Esling blends his background in mathematics and geology with his interests in hydrogeology and Quaternary stratigraphy.  His efforts have led to studies quantifying erosion rates in strip mine spoils, assessing the impact of agricultural drainage wells on shallow bedrock aquifers, determining the effect of underground refuse disposal on regional groundwater flow systems, and investigating the migration of contaminant plumes through shallow aquifers.

Esling works closely with his students investigating a variety of hydrogeologic and Quaternary stratigraphic problems in southern Illinois.  Developing analytic models to describe the groundwater flow systems that develop in response to mining activities, monitoring the hydrologic budget of coal refuse sites, and characterizing the material properties of surficial deposits, including hydraulic conductivity, are recent research projects. 

Esling is also active in developing innovative, interactive, simulations of physical systems including a quasi-three-dimensional radial finite-difference groundwater flow model, as well as particle tracking, flow vector, and random walk transport models.  He has extensive Pascal, Basic, and FORTRAN programming experience.  He authored Graphic Groundwater, a graphical interface to MODFLOW and MODPATH and has recently developed graphical interfaces to single well test simulation programs and baseflow simulation programs.
