Optimization provides a great tool for many applications related to public water distribution networks. Accurate modeling of network hydraulics and water quality requires real-time estimation of model parameters including network demands, and real-time data reconciliation and gross error detection. During normal operations, an accurate hydraulic model can be used for optimal planning that minimizes energy costs, and an accurate water quality model can be used to maintain chlorine requirements at minimum cost.  In the event of an accidental or intentional contamination in the water network, real-time response and recovery planning is required to efficiently and quickly minimize the health and economic impact.

This research focuses on development of dynamic models that describe the hydraulics and water quality in public water distribution networks. For network operation and security applications, we provide techniques where these models are embedded directly into the optimization formulation and solved simultaneously. Special attention is given to the development of fast and scalable algorithms that can help in solving these problems in real-time for large and complex networks.
