Negative pressures in full-scale distribution system: field investigation, modelling, estimation of intrusion volumes and risk for public health
Negative pressures full-scale distribution system field investigation public health
2010/9/20
Various investigations encompassing microbial characterization of external sources of contamination (soil and trenchwater surrounding water mains, flooded air-valve vaults), field pressure monitoring,...
A bottom-up approach of stochastic demand allocation in water quality modelling
stochastic demand allocation water quality modelling
2010/9/20
The study showed that the bottom-up approach leads to realistic water demand patterns and travel times, without the need for any flow measurements or calibration. In the periphery of the drinking wate...

Hydraulic modelling of drinking water treatment plant operations
drinking water treatment plant Hydraulic modelling
2010/9/20
The flow through a unit of a drinking water treatment plant is one of the most important parameters in terms of a unit's effectiveness. In the present paper, a new EPAnet library is presented with the...
Importance of demand modelling in network water quality models: a review
demand modelling network water quality models a review
2010/9/20
For the large diameter lines that comprise the transport portion of a typical municipal pipe system, a skeletonised network model with a top-down approach of demand pattern allocation, a hydraulic tim...
Importance of demand modelling in network water quality models: a review
demand modelling network water quality models a review
2010/9/20
For transport systems the current hydraulic models suffice; for the more detailed distribution system a network water quality model is needed that is based on short time scale demands that considers t...
