Non-standard Numerical Methods Applied to Subsurface Biobarrier Formation models in Porous Media

摘要

Biofilm forming microbes have complex effects on the flow properties of natural porous media. Subsurface biofilms have the potential for the formation of biobarri- ers to inhibit contaminant migration in groundwater. Another example of beneficial microbial effects is the biotransformation of organic contaminants to less harmful forms, thereby providing an in situ method for treatment of contaminated ground- water supplies. Mathematical models that describe contaminant transport with biodegradation Involve a set of coupled convection-dispersion equations with non-linear reactions.
