RISDiscussion of “Simulating Nonresidential Water Demand with a Stochastic End-Use Model” by E. J. M. Blokker, E. J. Pieterse-Quirijns, J. H. G. Vreeburg, and J. C. van Dijk
Publisher: American Society of Civil Engineers
Discussion of “Transient Flow Caused by Air Expulsion through an Orifice” by G. De Martino, N. Fontana, and M. Giugni
Publisher: American Society of Civil Engineers
Understanding Air Release through Air Valves
Publisher: American Society of Civil Engineers
Abstract: Water transients with entrapped air can originate large pressure peaks that can severely damage distribution networks. Entrapped air can have a damping or amplifying effect on these undesirable pressure peaks. Unfortunately, ...
Graphical Method to Calculate the Optimum Replacement Period for Water Meters
Publisher: American Society of Civil Engineers
Abstract: Calculating the optimum replacement period of meters has always been a major concern for water utility managers. Its determination is time-consuming and requires multiple calculations. This note presents a graphical method ...
Burst Detection in Water Networks Using Principal Component Analysis
Publisher: American Society of Civil Engineers
Abstract: The following work presents a multivariate statistical technique applied to the control of water inflows into district metering areas (DMAs) of urban networks. This technique, called principal-component analysis (PCA), ...
