INVERSE COUPLED THERMAL- HYDRO-BIO-GEOCHEMICAL (THBC) MODELS FOR POROUS AND FRACTURED MEDIA
This paper presents a formulation of inverse coupled models of flow, reactive solute transport and biogeochemical processes in porous and fractured media. The inverse problem is formulated as the minimization of a generalized least-squares criterion by means of a Gauss-Newton-Levenberg-Marquardt method. The solution of the inverse problem provides simultaneous estimates of flow, heat, solute transport, microbial and geochemical parameters from available hydraulic head, water flux, water content, temperature, aqueous and total concentration data as well as prior information on model parameters. The mathematical formulation of the Thermal-Hydro-Bio-geoChemical (THBC) inverse model has been implemented in a finite element code, INVERSE-BIOCORE2D, which has been verified with synthetic examples and tested for the estimation of microbial parameters in a laboratory experiment and the in situ REX experiment performed at the Aspo Hard Rock laboratory in Sweden.
