The BATtle of the Attack Detection ALgorithms (BATADAL) is most recent competition on planning and management water networks undertaken within Water Distribution Systems Analysis Symposium. goal battle was to compare performance algorithms for detection cyber-physical attacks, whose frequency has increased in last few years along with adoption smart technologies. design challenge set C-Town network, a real-world, medium-sized distribution system operated through programmable logic...
The core idea behind sectorization of Water Supply Networks (WSNs) is to establish areas partially isolated from the rest network improve operational control. Besides benefits associated with sectorization, some drawbacks must be taken into consideration by water operators: economic investment both boundary valves and flowmeters reduction pressure system resilience. target properly balance these negative positive aspects. Sectorization methodologies addressing aspects mainly consider costs...
A novel methodology to sectorize water supply networks (WSNs) depending on a main transmission line is presented in this paper. The based concepts derived from the social network theory and graph (namely, community detection shortest path respectively); also multi-objective optimization process by means of agent swarm (ASO). series energy, operative, economic criteria are optimized process. core idea form sectors over distribution communities found using algorithm (Walktrap). flexible...
Management of large water distribution systems can be improved by dividing their networks into so‐called district metered areas (DMAs). However, such divisions must based on appropriated technical criteria. Considering the importance deeply understanding relationship between DMA creation and these criteria, this work proposes a performance analysis generation that takes account indicators as resilience index, demand similarity, pressure uniformity, age (and thus quality), solution...
Water supply utilities need to properly manage their systems guarantee a quality supply. One way large is through division into district metered areas (DMAs). Graph clustering with an unknown number of subdivisions, as in social network theory, has proven highly efficient this sectorization problem. Several physical and hydraulic features may easily be used criteria suitably divide the network. This paper uses community detection algorithms define several DMA scenarios. Configurations mainly...
Intermittent supply is a common way of delivering water in many developing countries. Limitations on and economic resources, addition to poor management population growth, limit the possibilities 24 h day. networks are usually designed managed an empirical manner, or using tools criteria devised for continuous systems, this approach can produce inequity. In paper, based hydraulic capacity concept, which uses soft computing graph theory cluster analysis, developed define sectors, also called...
Abstract Sectorization is a process aimed at efficiently managing Water Supply Networks (WSNs). There are many large WSNs where the number of sectors into which they might be subdivided initially unknown. Our method uses concepts derived from Social Network Theory (SNT) such as centrality and community detection to obtain subdivisions. The output then evaluated through energy criteria. This methodology entails two very important benefits over other methods previously proposed. Firstly, it...
Water supply systems have been facing many challenges in recent decades due to the potential effects of climate change and rapid population growth. need expand because demographic Therefore, evaluating increasing system capacity is crucial. Specifically, we analyze network as one main features a system. When starts decrease, there risk that continuous will become intermittent. This paper discusses how expansion carried out throughout life span typically reduces capacity, thus transforming...
Water distribution systems are critical infrastructures that can be the subject of various types attacks. Concerns range from biological and chemical intrusions in pipelines to operational issues water control assets. Cyber-attacks have also turned today into a crucial issue consider. In highly automatized infrastructures, cyber-attacks considered as non-planned actions changing system operation non-expected scenarios. They potentially produce unavailability enough appropriated for public...
This document shows some aspects regarding water leakage time propagation through the underground, in controlled laboratory conditions, using a drilled PVC pipe, interpretation of GPR images.

Selecting the most appropriate heuristic for solving a specific problem is not easy, many reasons. This article focuses on one of these reasons: traditionally, solution search process has operated in given manner regardless being solved, and been same size, complexity domain problem. To cope with this situation, processes should mould into areas space that are meaningful builds previous work development multi-agent paradigm using techniques derived from knowledge discovery (data-mining...
