Recent water quality studies have emphasized the need for transient analysis of large pipe networks to properly assess the potential level of intrusion associated with negative pressure and the resulting effect on disinfectant residual efficiency. Tr

Many surge analysis and design rules have evolved overtime to help utilities cope with the complexity of transient phenomena. These rules have been widely applied to simplify analysis by restricting both the number and difficulty of the transient cas

For most piping systems the maximum and minimum operating pressures occur during transient operations. Therefore it is essential to good design and operation to perform a transient analysis for normal startup and shutdown and for unplanned events suc

The authors compared two numerical methods-one Eulerian-based, the other Lagrangian-based-for modeling hydraulic transients in water distribution systems. The method of characteristics (MOC), considered to be the most accurate of the Eulerian methods

Transients can introduce large pressure forces and rapid fluid accelerations into a water distribution system. These disturbances may result in pump and device failures, system fatigue or pipe ruptures, and even the backflow/intrusion of dirty water.

A variety of normal water distribution system operations will result in pressure fluctuations that can possibly lead to the occurrence of relatively brief (transient) low or negative pressures at various locations of the system, thus creating the pot

The validity of a hydraulic network model of a water distribution system depends largely on the accuracy of input data and the assumptions made in developing the model. Although much of the data can be obtained with a high degree of certainty, certai
