  • Development and application of coupled surface/subsurface flow and contaminant models
  • Theory of single- and multi-phase flow and mass transport in complex subsurface environments
  • Numerical analysis, advanced algorithm development
  • Geostatistics, data analysis


Professor Sudicky studies the mathematical modelling of groundwater flow and contaminant transport in hydrogeologic systems by numerical and analytical methods. His research involves groundwater remediation; stochastic analysis of flow and mass transport in heterogeneous porous and fractured geologic media; groundwater hydraulics and statistical characterization of spatial variability of material properties at field sites; theory and modelling of surface/subsurface flow; and solute and energy transport from the watershed to the continental scale.


Professor Sudicky's course offerings have included Physical Hydrogeology, Flow Through Porous Media, Statistics and Mathematical Methods in Geology.
