paper focuses on the evaluation of network performance during an operational period, taking into account pipe roughness … uncertainty. A network analysis is performed by generating probabilistic series of pipe roughness using Monte Carlo simulation … (MCS) in the operational period of the Two-loop WDN. Results show that an increase in pipe roughness uncertainty causes a …
