Abstract
Abstract. Hydraulic state estimation in water distribution networks is the task of
estimating water flows and pressures in the pipes and nodes of the network
based on some sensor measurements. This requires a model of the network as
well as knowledge of demand outflow and tank water levels. Due to modeling
and measurement uncertainty, standard state estimation may result in
inaccurate hydraulic estimates without any measure of the estimation error.
This paper describes a methodology for generating hydraulic state bounding
estimates based on interval bounds on the parametric and measurement
uncertainties. The estimation error bounds provided by this method can be
applied to determine the existence of unaccounted-for water in water
distribution networks. As a case study, the method is applied to a modified
transport network in Cyprus, using actual data in real time.
