Control analysis for water quality problem

Institut de Recherche Math´ematique Avanc´ee, Universit´e Louis Pasteur, 7 rue Ren´e Descartes, 67084 Strasbourg Cedex,France.The optimal control of water quality model is considered. We analyze a regularized version of the pointwise control. Anumerical algorithm is presented. The solution approach is a combination of a TVD scheme for the shallow water equationsand a purley deterministic particle method for the pollutant problem. We present some computational results.
