Existence of a solution and functional spaces.Includes bibliographical references and index.Inverse problems in pollution, where incomplete data forces the practitioner to work backwards from effects to determine causes, are a particularly challenging problem for environmental scientists and mathematicians. This useful guide explains how to solve inverse problems by measuring pollution concentration at a few points and  using the sentinel method  locate and identify pollutants, calculate the quantity of pollutant discharged, detect crises early, and more. This applicationsoriented book also explains how to extend the method to other situations.
