Management of Contamination Risks and Identification of Contamination Sources

Some aspects of management of contamination risks based on monitoring contamination sources areunder consideration. The case when direct measurements are impossible and the values of the contaminationinputs should be estimated through observations of indirect indicators is studied. Standard mathematical modelsdescribing the diffusion of a contaminant in the form of partial differential equations of the parabolic type areused. A model-based technique for the reconstruction of the evolution of the intensities of point-concentratedcontamination sources through observations of the concentration of the contaminant is presented. Results ofnumerical experiments are discussed.
