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 ...

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 ...

Decomposition of Water Distribution Networks

A I I E Transactions, 1976
Abstract This paper generalizes the class of design problems for water supply systems which can be solved by mathematical programming. The goal is to design a least cost water supply system to satisfy minimal pressure head requirements at specified rates of usage for multiple customers.

Security Issues in Drinking Water Distribution Networks

2008
This paper formulates the security problem of sensor placement in water distribution networks for contaminant detection. An initial attempt to develop a problem formulation is presented, suitable for mathematical analysis and design. Multiple risk-related objectives are minimized in order to compute the Pareto front of a set of possible solutions; the ...

Sampling design for water distribution network

2003
Modeling activities, specifically model calibration, need sensor measurements. Since data collection is expensive and time-consuming, ineffective measurements should be avoided. For this reason, it is important to have a method for designing the field data collection that will give the most useful information.

Optimization of water distribution networks

Journal of Hydraulic Research, 1996
In this study, a computer program is developed which enables us to design a water distribution system which satisfies all constraints including pipe diameters, low velocities, and nodal pressures with a minimum total cost. The hydraulic analysis of the water distribution system is performed by the Newton-Raphson method.

Districting Methods for Water Distribution Networks

Growing awareness of environmental issues and the need for sustainable resource management increasingly underscore the importance of water as a finite and valuable resource. Despite this recognition, many water distribution systems suffer from significant inefficiencies, including excessive leakage, limited preventative measures, and a predominately ...

Distributed estimation and control of water distribution networks by logical consensus

2014 6th International Symposium on Communications, Control and Signal Processing (ISCCSP), 2014
In this study we present a methodology for backflow detection through the interpretation of results from a network of Automatic Meter Reading. The approach is based on the so-called logical consensus theory and consists of a distributed failure detection and system reconfiguration.
