EXPLICIT MATHEMATICAL-MODELS OF DISTRIBUTION STORAGE WATER-QUALITY

Explicit analytical mathematical models for use in water-quality simul ation studies and management of distribution-system storage are develo ped, The proposed models can be used effectively for investigating the mixing characteristics of tanks and subsequent effects on water quali ty, and can directly supplement any of the existing distribution-syste m water-quality simulators; These models are formulated analytically f rom mass-balance principles, where specific hydrodynamic processes are modeled conceptually. The resulting models are simple to understand a nd implement and are well suited to the needs of those practicing engi neers who wish to write and run their own programs. The performance of the models is illustrated by application to actual tank data taken fr om a previous paper. Enhancement of distribution-system water-quality management is a principal benefit of the developed models.
