On the estimation of contamination sources from downstream concentration measurements

Abstract

The estimation of contamination source parameters from concentration measurements at certain lines is considered in a variational statement. The corresponding optimality condition and the adjoint problem are formulated. Both direct and adjoint problems are calculaled by a fmite difference method. The optimization problem is solved in the iterative way. The non-uniqueness of the problem is considered and managed with using the additional information for sources. The numerical tests demónstrate the feasibility for the single source coordinates estimation.
