Full Description

Skeletonization, the process of representing a waterdistribution network model by selected pipes, can bebeneficial for steady-state analysis by providing improvedcomputational performance. However, use of networkskeletonization for surge analysis may lead to ineffectivedesign recommendations, leaving the system poorly protectedand vulnerable to both catastrophic failure andcontamination from the external environment.The rules of skeletonization ignore the pipe propertiesof a distribution system as well as the inherentproblem of interaction of surge waves in the differentcomponents. The transient response is strongly sensitiveto system-specific characteristics, so any carelessskeletonization can lead to inaccurate results and inadequatesurge protection.If care is exercised, however, traditional networkskeletonization procedures can be successfully adaptedfor transient analysis. Properly defined models caneffectively estimate intrusion potential, identify criticalregions in the distribution system that are at risk oflow- or negative-pressure surges, and evaluate howsuch surges may be avoided and/or controlled.
