Reliability based rehabilitation of water distribution networks by means of Bayesian networks

Journal of Water and Land Development, 2017
Water plays an essential role in the everyday lives of the people. To supply subscribers with good quality of water and to ensure continuity of service, the operators use water distribution networks (WDN). The main elements of water distribution network (

Occurrence of Transients in Water Distribution Networks

Procedia Engineering, 2015
AbstractThe common existence of pressure transients in operational water distribution systems (WDS) requires their characterisation and assessment of their impact. This paper performs such characterisation by evidencing the occurrence and the differences in pressure transient behaviour in complex WDS.

Planning Water Distribution Network Renewal Using the SAM Model for Data Analysis of Historical Events [PDF]

آب و فاضلاب
One of the most crucial decisions for water and sewerage companies is how to strategize network renewal activities. Any misstep in this area can result in wasted allocated funds and the emergence of issues related to water distribution networks ...

Fate and behaviour of Microplastics (> 25µm) within the water distribution network, from water treatment works to service reservoirs and customer taps.

Water Research
Water treatment works have previously shown high efficiency in removing microplastics > 25 µm from raw source water. However, what is less well known is the extent to which microplastics of this size class are generated or lost within the water ...

Scaling-Laws of Flow Entropy with Topological Metrics of Water Distribution Networks

Entropy, 2018
Robustness of water distribution networks is related to their connectivity and topological structure, which also affect their reliability. Flow entropy, based on Shannon’s informational entropy, has been proposed as a measure of network redundancy and ...

ST-GPINN: a spatio-temporal graph physics-informed neural network for enhanced water quality prediction in water distribution systems

npj Clean Water
Data-driven models often neglect the underlying physical principles, limiting generalization capabilities in water distribution systems (WDSs). This study presents a novel spatio-temporal graph physics-informed neural network (ST-GPINN) for water quality
