SOME ISSUES CONCERNING THE PROBLEMS OF WATER QUALITY MODELING IN DISTRIBUTION SYSTEMS

Abstract: Some issues concerning the most popular practical problems encountered during modeling the water quality in water distribution systems were presented. The mathematical basis of water quality modeling, commonly understood as chlorine distribution modeling, covering the governing equations, initial and boundary conditions description as well as required and necessary simplifications, were discussed. Then, the most popular computer models of water quality in distribution systems used in environmental engineering practice, such as: input-output (I/O) model, inverse chlorine decay model and forward simulation, were introduced. The modeling assumptions, model structure and limitations, advantages and disadvantages of given models were also discussed
