My research has focused on near-surface materials & processes including field-scale measurements & process-based modeling of soil gas and aqueous transport through sediments, soils, and waste.  A major area of interest has been landfill gas generation, transport & emission processes, as well as the technology for commercial-scale landfill CH4 utilization.   Recent investigations using a new field-validated model (CALMIM) have focused on how seasonal climate influences CH4 emissions inclusive of oxidation from various cover soils at specific sites. Collaborators during 4 decades have included university researchers, Federal & state research groups, international research & regulatory agencies, private industry, and municipalities in the U.S., Europe, Africa, Australia, and Asia.

Recent projects include:

  • Improved modeling of landfill CH4 emissions [CALMIM model: see below].  Funded by (1) California Energy Commission, Sacramento, CA 2007-2010
  • Environmental Research & Education Foundation (EREF), Raleigh, NC 2011-2014
  • Emissions of high global warming potential GHGs from California landfills.  Funded by California Air Resources Board under subcontract to UIC from California Polytechnic State University:
  • Effect of biochar-amended cover soils on landfill CH4 emissions and oxidation.  Co-P.I., National Science Foundation grant to Dr. Krishna Reddy, Dept. of Civil & Materials Engineering, UIC:

Overview of CALMIM Model:

Working with Kurt Spokas of the U.S. Dept. of Agriculture-Agricultural Research Service (USDA-ARS), St. Paul, MN during the last decade, a new process-based GHG inventory model for landfill CH4 emissions was developed and field-validated.  CALMIM [CAlifornia Landfill Methane Inventory Model], which originally focused on California sites, was improved and internationally field-validated at >25 sites in N. & S. America, Europe, Asia, Australia, and Africa.  Via  embedded globally-validated USDA climate models with user-supplied information for latitude/longitude, cover materials, boundary conditions & engineered gas recovery, CALMIM models 1-D bidirectional diffusional transport of CH4and O2 over a “typical annual cycle” [365 d] for individual cover soils at any site worldwide.  Using 10-min time-steps and 2.5 cm depth increments, variable CH4 transport and emission rates are related to both fixed and transient soil properties including laboratory-derived relationships for oxidation relative to soil temperature and soil moisture potential.  CALMIM includes the major drivers for emissions known from literature: e.g., the physical properties & thickness of site-specific soils, the seasonality of gaseous transport & oxidation in cover materials, and site design & operational factors including cover areas & implementation of gas recovery.  CALMIM can improve quantification of landfill sources for urban and regional GHG inventories inclusive of multiple CH4 sources with high individual uncertainties.  This JAVA tool is compatible with PC, MAC/OS, and UNIX systems and is freely available using the following link.
