A novel pressure-based leakage assessment and characterisation method was applied to a range of bulk pipelines in the field to evaluate the practical application of the method. With this method, th...

Fluid pressure influences leakage flow rate in water distribution pipe networks. Significant progress has been made in the use of pressure management techniques to control leakage. An empir...

Urban water systems can be highly energy intensive. Yet, they are also excellent candidates for demand-response since they possess readily controllable operations and large amounts of storage. However, real-worlds trials have delivered mixed results,

Much progress has been made over the last decade in understanding the behaviour of flow through leak openings with changes in water mains pressure. In particular it has been established that variations in leak areas with pressure is the main factor r

It has been well established in several experimental and modeling studies that leak areas are often not fixed, but vary as linear functions of pressure. Replacing this linear equation into ...

This study investigated the feasibility of characterising the pressure-leakage response of water distribution systems using the FAVAD (Fixed and Variable Area Discharges) equation, instead of the conventional N1 power equation. The study was based on

The hydraulics of leakage and intrusion flows through leak openings in pipes is complicated by variations in the leak areas owing\ud to changes in pressure. This paper argues that the pressure–area relationship can reasonably be assumed to be a lin
