Short summary
Using real-time uncertain measurements from a real water transport network, the proposed Iterative Hydraulic Interval State Estimation algorithm generates bounds on hydraulic states, by taking into account the measurement uncertainty and modeling uncertainty in the form of uncertain pipe parameters. The applicability of this methodology was demonstrated by using it to estimate the unaccounted-for water in the network. This methodology can be used as a tool for fault detection in water networks.
