A transient 2-D water quality model for pipeline systems

This study develops a water quality model in a pipeline during transient conditions using a two-dimensional (2-D) approach including advection, diffusion, and reaction terms. More specifically, using a modifiedVardy-Hwang hydraulic model, a 2-D transient model for flow is coupled with a 2-D advection-diffusion-reaction model for chemical constituent concentration.A five-region turbulence model is used to compute turbulent shear stresses.
