3D Representation of (Buried) Water Supply Elements using Pre-Processed GPR Images

Ayala Cabrera, David; Ocaña Levario, Silvia Janeth; Izquierdo Sebastián, Joaquín; Pérez García, Rafael (2015)

[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 hybrid multicriteria approach to GPR image mining applied to water supply system maintenance

Carpitella, Silvia; Ocaña-Levario, Silvia Janeth; Benítez López, Julio; Certa, A.; Izquierdo Sebastián, Joaquín (Elsevier, 2018)

[EN] Data processing techniques for Ground Penetrating Radar (GPR) image mining provide essential information to optimize maintenance management of Water Supply Systems (WSSs). These techniques aim to elaborate on radargrams ...
Análisis, caracterización y modelación 3D de fugas de agua en sistemas de abastecimiento de agua mediante imágenes de GPR

Ocaña Levario, Silvia Janeth (Universitat Politècnica de València, 2021-03-04)

[ES] Los esfuerzos que hacen los países, en conjunto con organizaciones mundiales, tales como IWA (por International Water Association), ONU-Agua y OMS (Organización Mundial de la Salud), para mitigar el impacto ambiental ...
GPR image analysis to locate water leaks from buried pipes by applying variance filters

Ocaña-Levario, Silvia Janeth; Carreño-Alvarado, Elizabeth Pauline; Ayala Cabrera, David; Izquierdo Sebastián, Joaquín (Elsevier, 2018)

[EN] Nowadays, there is growing interest in controlling and reducing the amount of water lost through leakage in water supply systems (WSSs). Leakage is, in fact, one of the biggest problems faced by the managers of these ...
GPR-based water leak models in water distribution systems

Ayala Cabrera, David; Herrera Fernández, Antonio Manuel; Izquierdo Sebastián, Joaquín; Ocaña Levario, Silvia Janeth; Pérez García, Rafael (MDPI, 2013-12)

[EN] This paper addresses the problem of leakage in water distribution systems through the use of ground penetrating radar (GPR) as a nondestructive method. Laboratory tests are performed to extract features of water leakage ...
Probabilistic maps for buried pipes location based on GPR images

Ayala Cabrera, David; Izquierdo Sebastián, Joaquín; Pérez García, Rafael; Ocaña Levario, Silvia Janeth (2014)

In this work, statistical methodologies are used to generate automatic probabilistic maps of pipe layouts in water supply systems (WSS) based on street surveys using ground penetrating radar (GPR). Probabilistic maps ...
Reconocimiento de patrones para la identificación de tuberías enterradas en sistemas de abastecimiento de agua a partir de imágenes de GPR

Ocaña Levario, Silvia Janeth (Universitat Politècnica de València, 2015-07-27)

[EN] This document is proposed with the objective to create a first approach through the development of a methodological tool that allows an automatic localization of pipelines in the water supply systems (WSS), by using ...
