Cadastral Misinformation and Its Effects on the Hydraulic Behavior of Water Distribution Networks and Their Models Calibration

Abstract

This article presents the results of a theoretical research on the effects cadastral misinformation on the simulation and calibration of Water Distribution Networks (WDN). It describes the developed methodology used to determine the effect that these mistakes have on the hydraulic response and calibration WDN models. Those effects were evaluated both for important pipes and different sets of unimportant pipes from the hydraulic point of view. The research proved that the Resilience Index is directly proportional to the effect produced by a mistake. In addition, the calibration methodology developed could be used to locate the cadastral mistakes. This means the hydraulic model could be used as a tool to improve water utilities WDN management. Finally, the methodology validated the use of skeletonized models.
