TLDR
In this article, the transition from pressurized to partial flow regime is modeled in WWDNs, and the transient flow conditions, including the transitions from partial flow to full flow, are incorporated.Abstract:
Modeling intermittent water distribution networks (WDNs) requires effective incorporation of the transient flow conditions, including the transitions from pressurized to partial flow regime...read more

Energy and Hydraulic Efficiency in Intermittent Operation of Water Distribution Networks
TL;DR: In this paper , the authors studied different levels of intermittency as a strategy to operate under severe water scarcity conditions and identify the gains that can be made in leakage reduction, combined with optimal pump operation, to maintain operational costs at the same level, or better, as continuous operation.

Water Distribution Reliability: Simulation Methods
TL;DR: Simulation enables computation of a much broader class of reliability measures than do analytical methods, but it requires considerably more computer time and its results are less easy to generalize.
Journal ArticleDOI
A technical note on the inclusion of pressure dependent demand and leakage terms in water supply network models
TL;DR: In this article, a technique for including pressure dependent demand and leakage terms in simulation models for water distribution systems is proposed, which leads to more realistic simulation results when the network pressures are too low to provide specified consumer demands, or high enough to cause significant leakage losses.

Comparison of Methods for Predicting Deficient-Network Performance
Rajesh Gupta,Pramod R. Bhave +1 more
TL;DR: In this article, the parabolic head-discharge relationship (no flow at minimum head to required flow at desirable head) is used to predict the deficient-network performance of a water distribution system.

Comparing microbial water quality in an intermittent and continuous piped water supply.
Emily Kumpel,Kara L. Nelson +1 more
TL;DR: Tap water from intermittent supply had significantly more indicator bacteria throughout the rainy season compared to the dry season, and drinking water samples provided by households in both continuous and intermittent supplies had higher concentrations of indicator bacteria than samples collected directly from taps.
