Abstract: Uncertainty about the status of valves in a water distribution system, or the existence of total blockages, is not uncommon. This paper presents an approach for determining topological changes using transient response analysis. Precise information is not available regarding all the physical elements contributing to the transient response of a water distribution system. Thus a parameterised model is developed and calibrated to represent 'real' transient responses from a field water distribution system. The robustness of this model, and the methodology for diagnosing topological changes, are confirmed when used to successfully identify closed valves in the field.
