Data-driven methods based on samples from a supervisory control and data acquisition system have been widely applied in water-supply-network burst detection to save unexpected economic labor costs. However, the class imbalance problem actual on-site monitoring needs be revised improve performance of data-driven methods. In this study, we proposed domain adaptation method generate minor-category...

The implementation of effective strategies to manage leaks represents an essential goal for all utilities involved with drinking water supply in order to reduce water losses affecting urban distribution networks. This study concerns the early detection of leaks occurring in small-diameter customers’ connections to water supply networks. An experimental campaign was carried out in a test bed to ...

Water distribution network (WDN) consists of several elements the main ones: pipes and valves. The work developed in this article focuses on a water supply prediction in the short and long term. To this end, reliability data were conjugated in decision making tools on water distribution network rehabilitation in a forecasting context. The pipes are static elements that allow the transport of wa...

[1] The influence of a single fracture intersection on density-driven immiscible flow is compared between wetting (water into air) and nonwetting (Trichloroethylene into water) flows. At low supply rates, the intersection acted as a hysteretic gate to pulsed flow of the wetting phase, but had minimal influence on nonwetting phase flow. For both cases, increasing the supply rate led to the forma...

The rational distribution of water in a water supply network (WSN) is a complex problem, especially for systems of large scale. Its complexity is continually increasing from the point of view of technical management. The division of WSN into hydraulic zones is a partition of the supply network into subsystems with controlled inputs and outputs, building smaller independent networks. This soluti...

neurotoxicants present in water supply may affect human functions in terms of attention, response speed and perceptual motor speed. neurobehavioural performance can be influenced by gender, age and education levels. this study aims to assess the neurobehavioral performance of palm oil estate residents with private water supply in southern peninsular of malaysia.a total of 287 and 246 participan...
