Skeletonization, the process of representing a water
distribution network model by selected pipes, can be
beneficial for steady-state analysis by providing improved
computational performance. However, use of network
skeletonization for surge analysis may lead to ineffective
design recommendations, leaving the system poorly protected
and vulnerable to both catastrophic failure and
contamination from the external environment.
The rules of skeletonization ignore the pipe properties
of a distribution system as well as the inherent
problem of interaction of surge waves in the different
components. The transient response is strongly sensitive
to system-specific characteristics, so any careless
skeletonization can lead to inaccurate results and inadequate
surge protection.
If care is exercised, however, traditional network
skeletonization procedures can be successfully adapted
for transient analysis. Properly defined models can
effectively estimate intrusion potential, identify critical
regions in the distribution system that are at risk of
low- or negative-pressure surges, and evaluate how
such surges may be avoided and/or controlled. Includes 28 references, figures.
