This powerpoint presentation begins by providing a brief overview of the city of Raleigh, North Carolina, and its water distribution system. Project objectives include: updating model for contamination simulations; identifying water system infrastructure vulnerability; developing an emergency response protocol; and, preventing the shutdown of the whole distribution system. Model development is presented, along with contamination simulations, and two case studies. Limitations of modeling approach include:lack of decay coefficient data of the contaminantsmakes model to simulate the contaminant asconservative chemical, which may over-estimatethe affected area; back-tracing the source of contamination is still achallenging job for model; and,the assumptions in the model, such as applyingthe same daily usage patterns to groupedcustomers, limit the result only as anapproximation of what happens in the real system.
