Description: This thesis studies the critical problem of water quality in a pipeline system considering the fate of disinfectant, the corrosion of the system, and the change in turbidity of water. The dissertation investigates a two-dimensional unsteady, multi-component, water quality model by coupling a mass transport equation including all transport mechanisms (namely advection, diffusion, and reaction) for the chemical constituents with a water hammer model. The decay/growth of the constituent is investigated with (but not limited to) a first-order reaction term. A suitable turbulence model is used to determine the velocity fluctuations and therefore the turbulence shear stresses and the corresponding diffusivity terms. The hydraulic and the mass transport equations are, then, coupled by two different numerical schemes; a finite difference method for the mass transport and the method of characteristics for the hydraulic part. Finally, the numerical results of the proposed model are compared with the results of available models in the literature.
