Item Modeling of in situ Biorestoration of Organic Compounds in Groundwater(1990-10) Chiang, C.Y.; Dawson, C.N.; Wheeler, M.F.A convergent numerical method for modeling in situ biorestoration of contaminated groundwater is outlined. This method treats systems of transport-biodegradation equations by operator splitting in time. Transport is approximated by a finite element modified method of characteristics. The biodegradation terms are split from the transport terms and treated as a system of ordinary differential equations. Numerical results of vertical cross-sectional flow are presented. The effects of variable hydraulic conductivity and variable linear adsorption are studied.
