Management of Contamination Risks and Identification of Contamination Sources

Abstract: Some aspects of management of contamination risks based on monitoring contamination sources are under consideration. The case when direct measurements are impossible and the values of the contamination inputs should be estimated through observations of indirect indicators is studied. Standard mathematical models describing the diffusion of a contaminant in the form of partial differential equations of the parabolic type are used. A model-based technique for the reconstruction of the evolution of the intensities of point-concentrated contamination sources through observations of the concentration of the contaminant is presented. Results of numerical experiments are discussed.
