Application of the Theil statistics to the calibration of a dynamic water supply model

This paper presents the procedures of the construction and calibration of hydraulic water supply system (WSS) models. In the research, the WSS in Cracow was used. The hydraulic model was built using the EPANET 2 computer program. For the evaluation of compatibility between operating parameters (pressure) obtained by simulation and real pressures in selected nodes (which form two time series) the Theil inconsistency statistics were applied. The method is not a very time consuming and allows us to find nodes at which the difference between the two time series is caused by a systematic error.
