This paper describes and demonstrates an efficient method for online hydraulic state estimation in urban water networks. The proposed method employs an online predictor-corrector (PC) procedure for forecasting future water demands. A statistical data-driven algorithm (M5 Model-Trees algorithm) is applied to estimate future water demands, and an evolutionary optimization technique (genetic algor...
This paper describes the development of WaterWiSe@SG, a wireless sensor network to enable real-time monitoring of a water distribution network in Singapore. The overall project is directed towards three main goals: 1) the application of a low cost wireless sensor network for high data rate, on-line monitoring of hydraulic parameters within a large urban water distribution system; 2) the develop...
Water distribution systems are vulnerable to aquaterrorism (terrorism attacks on the water supply) because they are extensive, relatively unprotected, accessible, and often isolated (USEPA 2002, 2003a, Grayman, 2002; Mays, 2004). An emerging activity in the water security arena is developing methods to minimize the public health and economic impacts of a large-scale attack. An intense effort is...
Prishtevka River Basin in the upper part is characterized by hilly - mountain terrain, while the side stretched towards the city of Pristina to the estuary of Sitnica River is characterized by field terrain. 1.5% of the catchment area is situated at an altitude above 1000 m, 33.9% from 1000 m to 800 m, 20.1% from 800 m to 700 m, 25.2% from 700 m to 600 m, and 19, 2% at an altitude below 600 m. ...
Evaluating Coliform Monitoring Strategies for Contamination Scenarios in a Distribution System Model
Large public water utilities currently are required to take several 100 mL water samples every month in their distribution systems and to test these samples for the presence of total coliforms to comply with the Total Coliform Rule. How and where they take these samples is not specified. The Total Coliform Rule is currently undergoing review and revision. One possible revision is more specific ...
power transformers provide a vital link between the generation and distribution of produced energy. such static equipment is subjected to abuse during operation in generation and distribution stations and leads to catastrophic failures. this paper reviewed the techniques in the field of condition monitoring of power transformers in recent years. transformer monitoring and diagnosis are the effe...
