This paper presents some aspects of the time propagation of underground water leakage in controlled laboratory conditions using a drilled polyvinyl chloride (PVC) pipe and interpreting ground penetrating radar (GPR) images. ...
[EN] In this paper, a ground penetrating radar (GPR) is used as a non-destructive
method to assess the buried elements of water supply systems (WSSs). The aim
is the detection of various pipe materials (such as plastic ...
A novel methodology to sectorize water supply networks (WSNs) depending on a main transmission
line is presented in this paper. The methodology is based on concepts derived from the social
network theory and graph theory ...

Selecting the most appropriate heuristic for solving a specific problem is not easy, for many reasons. This article focuses on one of these reasons: traditionally, the solution search process has operated in a given manner ...
[EN] The core idea behind sectorization of water supply networks (WSNs) is to establish areas partially isolated from the rest of the network to improve operational control. Besides the benefits associated to sectorization, ...
Achieving consistency in pair-wise comparisons between decision elements given by experts or stakeholders is of paramount importance in decision-making based on the AHP methodology. Several alternatives to improve consistency ...
Matrices used in the analytic hierarchy process (AHP) compile expert knowledge as pair-wise comparisons among various criteria and alternatives in decision-making problems. Many items are usually considered in the same ...
AHP (analytic hierarchy process) is used to construct coherent aggregate results from preference data provided by decision makers. Pairwise comparison, used by AHP, shares a common weakness with other input formats used ...

Las fugas en los sistemas de distribución de agua están provocadas por todos aquellos fallos en las tuberías, accesorios o tanques de almacenamiento que provocan una pérdida de agua. La cantidad de agua que se pierde por ...
Carrión Sánchez, Laura(Universitat Politècnica de València, 2014-06-06)
[ES] Adoptar un enfoque proactivo en la toma de decisiones es fundamental en las políticas de control de fugas de un abastecimiento de agua urbana. Cada vez es más importante que intervengan todas las partes implicadas. ...
[EN] We introduce a methodology based on spectral measurements of graph theory to establish the relative importance of areas in water supply networks (WSNs). To achieve an efficient vulnerability analysis, we have made a ...
Ramos Martínez, Eva(Universitat Politècnica de València, 2016-05-02)
[EN] One of the main challenges of drinking water utilities is to ensure high quality supply, in particular, in chemical and microbiological terms. However, biofilms invariably develop in all drinking water distribution ...
Accurate measurement is of paramount importance when dealing
with precious liquids, as is the case of water. In irrigation, for example, where
concessions are granted, accurate measurement is essential for balancing ...
Ayala Cabrera, David(Universitat Politècnica de València, 2012-01-19)
En este trabajo se evalúa la viabilidad del método propuesto de análisis de radargramas para la caracterización de los componentes del sistema de abastecimiento en servicio, con la realización de ensayos de laboratorio, ...
