Efficient management of water resources is a growing global concern. In Brazil, most regions deal with problems related to high rates of water loss in distribution systems. This situation involves a complex environment with multiple decision-makers, several alternatives, and subjective variables. Therefore, its evaluations require interactivity, clarity, learning, and that plausible aspects be discerned...
The paper deals with a methodology of detecting and localizing leakages in water distribution networks. Two approaches are presented: based on a hydraulic model of the network, and based on approximate models and fuzzy classifiers. Moreover, a case study concerning applications of the methodology to a real network in Rybnik, Poland is presented. A pilot version of the system has been running since...
With the rapid urbanization in China, the protection of water environment is more and more important. Urban sewage pipe network service is a new technology to store and manipulate spatial data, integrated with attribute data of sewage pipe network. This paper described a digital management platform of the urban sewerage pipe network service system based on Geographical information system (GIS) and...
This paper has integrated the automatic monitoring system of water resources, and fully excavated the monitoring information contents, and introduced information fusion technology, and discussed and analyzed information collection and transmission and processing, and brought forward the system which has versatility and portability and scalability by using geographic information systems and databases...
Recently, with the wide use of on-line monitoring technique in urban water supply networks, pipe network crack diagnosis based on pressure and (or) flow analysis has become a major development direction home and abroad. Meanwhile, in order to solve complex pipe network problems, neural network technology has gained more and more public attention. This paper, in accordance with the actual situations...
Water quality monitoring is a prerequisite for water pollution control. The rapid development of remote sensing technology will provide a new technical support. In this paper, with the study of the Weihe River in Shaanxi Province, RWQMS (Remote-sensing Water Quality Monitoring System V1.0) is designed and implemented based on SPOT-5 remote-sensing image and the system structure and key technologies...
Luoyang city is a region which is short of water resources in total amount. According to the amount of the available water resources, it can only maintain status quo. But it is estimated that it will lack water resources 2.43×108m3/a in the year 2010. For ensuring the speedy and sustainable development of economy in Luoyang City, the development and utilization of water resources have become one of...
Computer-based water body environment monitoring and management are effective methods to protect water body resources. The monitoring and management information for environmental monitoring originates from environmental laboratories. The current environmental monitoring and management of the existence of information processing is too slow to meet the requirements. Water body monitoring and management...
A principal factor in sensor network design is energy efficiency. In this work, we propose to extend the lifetime of sensor networks using appropriate choice of sensor node distribution. The key idea of our scheme is to deploy more nodes in areas of extensive energy usage. Using this scheme of sensor node distribution, we use probabilistic angular routing to route data packets from the sensor nodes...
