In this paper, solution of inverse contaminant transport problems is studied, including nonlinear sorption inequilibrium and non-equilibrium mode. A precise numerical solver for the direct problem is discussed. The method isbased on time stepping and operator splitting with respect to the nonlinear transport, diffusion and adsorption. The nonlinear transport problem corresponds to a multiple Riemann problem and is solved by modified front tracking method. The diffusion problem is solved by a finite volume scheme and the sorption part is solved by an implicit numerical scheme. The solution of the inverse problem isbased on an iterative approach. The gradient of the cost functional with respect to the determined parameters is constructed by means of solution of the corresponding adjoint system. Numerical examples are presented for a 1D situation and for a dual-well setting with steady-stateflow between injection and extraction wells. |
