Detection of Contamination in Water Distribution Network

2013
Monitoring drinking water is an important public health problem because the safe drinking water is essential for human life. Many procedures have been developed for monitoring water quality in water treatment plants for years. Monitoring of water distribution systems has received less attention. The goal of this communication is to study the problem of

Adaptive control of water quality in water distribution networks

IEEE Transactions on Control Systems Technology, 2006
Based on investigating the spatially distributed input-output relationship of disinfectant residual in water distribution networks, this brief paper formulates the water quality control problem of multiple nodes in a decomposed adaptive control framework, with special consideration on the periodic variation of parameter uncertainty due to varying ...

A review of graph and complex network theory in water distribution networks: Mathematical foundation, application and prospects.

Water Research
Graph theory (GT) and complex network theory play an increasingly important role in the design, operation, and management of water distribution networks (WDNs) and these tasks were originally often heavily dependent on hydraulic models.

Reduction of water losses by rehabilitation of water distribution network

Environmental Monitoring and Assessment, 2017
Physical or real losses may be indicated as the most important component of the water losses occurring in a water distribution network (WDN). The objective of this study is to examine the effects of piping material management and network rehabilitation on the physical water losses and water losses management in a WDN.

NETWORK ANALYSIS FOR RESILIENCE EVALUATION IN WATER DISTRIBUTION NETWORKS

Environmental Engineering and Management Journal, 2015
Resilience is meant in this paper as the capability of a networked infrastructure to provide its service even if some components are failed: it depends both on net-wide measures of connectivity and the role of a single component. This paper has two objectives: first to show how a set of global measures can be obtained using techniques from network ...

Leakage Detection in Water Distribution Systems Based on Time–Frequency Convolutional Neural Network

Journal of water resources planning and management, 2021
Effectively detecting leaks is critical to improving leakage control management. Acoustic detection is one of the main leakage detection methods, and has been widely used in water utilities...

Application of machine learning in water distribution networks

Intelligent Data Analysis, 1998
This paper describes an ongoing work on the application of machine learning techniques in the domain of water distribution networks. This research is performed in the framework of the European project WATERNET, whose aim is to develop a system to control and manage water distribution networks. WATERNET is composed of a supervision system, a distributed

Water Distribution Networks

2014
A water distribution system is a complex assembly of hydraulic control elements connected together to convey quantities of water from sources to consumers. The typical high number of constraints and decision variables, the nonlinearity, and the non-smoothness of the head—flow—water quality governing equations are inherent to water supply systems ...

Modernizing Water Distribution Networks

Outlook on Agriculture, 2012
In many arid and semi-arid countries, traditional irrigation schemes have been modernized, with open channel networks replaced by new on-demand pressurized systems. In this study, this conversion is evaluated using performance indicators derived both before and after the modernization of an irrigation district (Bembézar MD) in Andalusia, southern ...
