Mathematical description of the concentration field of pollutants in different aquatic systems par-ticularly in rivers, open channel flows and reservoirs is presented. Pollutants are defined here as all kinds of chemical substance that mix readily with water but do not react with it. It is assumed that the pollutants are passive but do not have to be conservative. The heat is also treated as a pollutant and it is shown how to describe the temperature field in the considered aquatic environment. Water flows in rivers, open channels and reservoirs are usually turbulent and the concentration calcula-tions need special treatment. It is shown how to describe mathematically the concentration distribu-tion in turbulent flows and also in shallow rivers and very long rivers. The pollutant transport in shallow rivers is treated as two-dimensional case and in very long rivers as one-dimensional case. The processes of dispersion in two-dimensional and one-dimensional cases are discussed.
