Of this concern, electrochemical corrosion has always been the persistent problem sparking off material degradation and therefore sometimes a tremendous harmful consequence accompanied. From time to time, an aging pipe with a minute rupture appears will obviously pose problem of product safety, environmental affair and in some instances, could be a catastrophe. Nevertheless, there have been only several investigations into the localized accelerated dissolution of iron and tended to focus on understanding the degradation of metallic pipe. To tackle this matter, an artificial corrosion system was initially installed to examine removed iron amount in mass using Faraday laws. This primary data could be a prerequisite for further comparisons to see the critical factors and therefore expect to have a rough estimation of pipe’s remaining strength.

Coping with uncertainty PB - Asociación Internacional de Hidrogeólogos – Grupo Español CY - Malaga SN - 9788493804633 PY - 2019 SP - 789 UR - https://m2.mtmt.hu/api/publication/31205046 ID - 31205046 AB - Today, securing, utilizing drinking water reasonably and excluding water loss are drawing multisectors’ primary international and national concern. As a result of the ruptures in aging distribution networks, a considerable amount of water loss is challenging the water utilities and authorities. The critically important issue is how to locate leakage among a colossal water mains, of them the contributed pipes are usually made of diverse materials and laid at different depths underground. The present work emphasized some practical geophysical methods for conduits tracing such as: ground penetrating radar (GPR), magnetometer, multichannel resistivity induce polarization (IP) and electromagnetic locator, drew a comparison between them. Regarding leakage detection techniques, after briefly refering to all of the water loss analysis, pressure management, acoustic methods, and remote sensing-based method, this research recommended some ways to unify these methods. The proposed combination of traditional and novel methods helps elevate the advantages and neglect the demerits of each method, significantly improve the efficiency in leakage detection technique. The paper took a Hungarian as a pilot study, that would be tangible evidence for water leakage detection in Central Euro, one of the most famous area for water resource management. Moreover, the authors have put forward several coherent theories to partly explain possible grounds of this declining water infrastructure that exist all over the world. Several geotechnical factors and possibly relevant geotechnical testing methods are also referred in order to put forward for further studies.
