Hydrometric network design using dual entropy multi-objective optimization in the Ottawa River Basin
Water resources managers commonly rely on information collected by hydrometric networks without clear knowledge of their efficiency. Optimal water monitoring networks are still scarce especially in the Canadian context. Herein, a dual entropy multi-objective optimization (DEMO) method uses information theory to identify locations where the addition of a hydrometric station would optimally ...

Discrete entropy theory for optimal redesigning of salinity monitoring network in San Francisco bay
The paper presents an entropy-based method for designing an optimum bay water salinity monitoring network in San Francisco bay (S.F. bay) considering maximum-monitoring-information and minimum-data-lost criteria. Due to cost concerns, it is necessary to design the optimal salinity monitoring network with a minimal number of sampling stations to provide reliable data. The monthly data recorded ...

Rieger and Vanrolleghem: monEAU: A platform for water quality monitoring networks
Abstract: Continuous monitoring of water quality creates huge amounts of data and therefore requires new concepts to guarantee high data quality and to prevent data graveyards. Monitoring stations commonly used in practice today suffer from insufficient flexibility and a lack of standardization. That is, although a lot of monitoring tasks are comparable and should lead to robust and powerful ...

Water quality comprehensive evaluation method for large water distribution network based on clustering analysis
In order to evaluate water quality for a large water distribution network comprehensively, a two-stage classification method was used and the clustering methods, self-organizing map (SOM), K-means method and fuzzy c-mean (FCM), were represented. With these clustering methods, the pipes of a large real water distribution network were divided into some groups considering one or more water quality ...

Stakeholder engagement in multi-objective optimization of water quality monitoring network, case study: Karkheh Dam reservoir
Reservoir water quality is important for water quality management downstream. A hierarchical approach is developed to present the monitoring locations within a format that satisfies the objectives of social stakeholders for making final decisions. First, a CE-QUAL-W2 model is applied to simulate water quality variables in the reservoir for a long time using a set of historic data. Second, ...

Optimal sampling network for monitoring the representative water quality of an entire reservoir on the basis of information theory
This study presents a method for optimal selection of sampling stations for representative and effective water quality monitoring of a reservoir on the basis of information theory. We adopt an objective function used for the design of other hydrological monitoring networks such as rain gauge networks. Unlike rain gauges, in which only a single variable of rainfall is of interest, water quality ...

Topological clustering as a tool for planning water quality monitoring in water distribution networks
Topological clustering was explored as a tool for water supply utilities in preparation of monitoring and contamination contingency plans. A complex water distribution network model of Copenhagen, Denmark, was simplified by topological clustering into recognizable water movement patterns to: (1) identify steady clusters for a part of the network where an actual contamination has occurred; (2) ...

Water distribution network robust design based on energy surplus index maximization
The aim of this paper is to show that energy surplus indices, such as resilience index, besides providing a very good indirect measure of water distribution network reliability, also represent a valuable and effective indicator of network robustness under alternative network scenarios. It can thus be profitably used for network design under conditions of uncertain future demands. The ...

Real-time data in the wild
Background The South African water resource (DWAF) monitoring network belongs to one of the well organized and managed networks world-wide. Well prepared and maintained measurement sites & stations deliver the data base for the water management in the huge territory of South Africa. One main issue of the online data availability is the data transfer from remote stations to the data centres. ...

Optimisation approach for pollution source identification in groundwater: an overview
Groundwater pollution occurs from different anthropogenic sources like leakage from Underground Storage Tanks (USTs) and depositories, leakage from hazardous waste dump sites and soak pits. Remediation of these contaminated sites requires optimal decision-making system so that the remediation is done in a cost-effective and efficient manner. Identification of unknown pollution sources plays an ...

MP 1 pump indispensable when measuring water quality - Case Study
Good surface and groundwater quality means sustainable development of plants, animals, and reliable drinking water. To guarantee this quality, a policy has been formulated in the Water Framework Directive which must be observed by all EU Member States. Due to the integration of various European water quality directives, the European countries are on the same page in terms of water-related issues, ...

Framework for water quality monitoring system in water distribution networks based on vulnerability and population sensitivity risks
Delivering water in sufficient quantity and acceptable quality is the main objective of water distribution networks (WDN) and at the same time is the main challenge. Many factors affect the delivery of water through distribution networks. Some of these factors are relevant to water quality, quantity and the condition of the infrastructure itself. The deterioration of water quality in the WDN ...
