Water losses have a high environmental impact in terms of natural resources depletion (water, energy, ecosystems). This work aims at developing an airborne water leak detection surveillance service to provide water utilities with adequate information on leaks in water transportation mains outside urban areas. As a first step, a series of measurement campaigns were performed with hyperspectral cameras and a thermal infrared camera for selecting the most appropriate wavelengths and combinations thereof for revealing at best high moisture areas and artificial leaks. Further measurements will be performed with thereby optimized instrumentation onboard a plane and a UAV in an operational environment.

the challenge of Leakage forecasting from pipelines has the potential to cause significant environmental damage and economic losses. While pipelines are designed and constructed to maintain their integrity, it is difficult to avoid the occurrence of leakage in a pipeline system during its lifetime. This review paper presents Systematic reviews of relevant published studies related to topics in machine learning (ML) and data analytic (DA) technologies, specifically, concerning distributed Water network leakage and Leakage forecasting methods from pipelines, published in the last nine years (2014-2022). This paper has been motivated by the lack of Systematic literature review articles that integrate water network failure and leakage modeling. Some of the existing practices reviewed the pipe condition and its failure. Others focused on the prediction models, whereas the rest outlined failure prediction models of large diameter mains only. The mainstream of the current practice, highlighted in this paper characterizes the structural deterioration and failure rates using various machine learning techniques, whereas the remainder of research covers a multiplying of machine learning methods to forecast and model the pipeline risk of failure. On top of this, this paper includes a fundamental understanding of the operating principles of currently available pipeline leak detection and prediction technologies. The review offers the models together with their proposed methodologies and algorithms, contributions and limitations and types of collected data used to develop the models using the systematic review method. Finally, future work and research challenges are recommended to assist the research community in setting a clear agenda for the upcoming research. To do so, we have conducted a systematic literature review of existing scientific researchers and defined a research agenda for the near future based on the findings and limitation identified in the literature Keywords

The paper presents the studies and researches on the natural and anthropic risk parameters on the Moldova riverbed in the Soci area, Iasi County. In this area are located hydrotechnical structures for regulation of the riverbed and shore defence for the protection of the undercrossing of the Timisesti-Iasi adduction pipeline. The theoretical study analyzed hydrological risk parameters (especially liquid and solid flows) recorded over the last 30 years. High flow rates have a high hydroclimatic risk for bed and river construction. Anthropogenic risk parameters were manifested in the morphological modification of the minor riverbed of the Moldova River. An important anthropogenic risk is the uncontrolled exploitation of the ballast in the bed and river banks of Moldova. The effects of this risk contributed to the descent of the bed of the bed at an accelerated pace, along with the erosion of the banks. The accumulation of the effects caused by the natural and the anthropic risks led t...

The paper presents research conducted on the optimization of urban water supply networks. One direction of optimization follows the use of GIS models for digitization on components system. The use of water supply system operation depends on the proper functioning of the structural and functional components.In the analysis it was found that the main components of the system are the following: capture, headrace, puming stations, reservoirs, distribution networks.Each component is made up of a multitude of sub-components with specific structural and functional character. Using GIS program it follows to specify custom properties using layers of structural and functional domains. Autocad Civil 3D, GisNet Set, ArcGis Server and Autocad Toolbase programs allowed to obtain thematic maps on specific areas of the system. The model of the study can vary from simple to complex and can be generalized to any water supply system for a specific use (urban area, villages, tourist resorts, shopping c...

A partir del modelo lineal de dimensión infinita del gas en el ducto junto con condición de falla, se deriva la respuesta caracteŕıstica que definen los transitorios asociados con los eventos anormales. Aśı, las respuestas de la presión transitoria en un punto de registro en la tubeŕıa, validan resultados emṕıricos usados para la detección de fallas en una tubeŕıa de gas.

An Unmanned Aerial Vehicle (UAV) supply chain architecture is used to handle flood water leak incidents occurred by physical disasters in Smart Cities (SCs). Floods produce serious problems and inefficiencies in problematic sectors of water grid. Such incidents are treated as a supply chain problem, where each incident is assigned to a certain priority. On a trigger occurrence the nearest UAV reaches a certain flood water leak incident where the assigned plumber at the SC control system assesses the problem. SC personnel evaluate if it is a high significance incident to fix the problem in real time. In this paper, there are presented certain use cases, which are evaluated with proposed metrics incorporated by control system supply chain architecture to infer the optimum use case for SC recovery. Such a use case is proposed to be adopted by SC control system architecture to handle upcoming scenarios of flood physical disasters.

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 GPR (Ground Penetrating Radar) as a non destructive inspection technique. To do so, a methodology that permits identification and patterns extraccion through image analysis previously obtained by the GPR. To develop this job, laboratory essays were done under controlled conditions on a dry-soil filled tank, where 4 diferent materials pipelines were previously buried; afterwards, GPR prospections were taken over the tank. Radargrams or GPR images were obtained by doing so, beeing the starting point to develop this investigation. Next, images were subjected through different procedures to identify patterns. After applying the past procedures results were obtained first of all upgrading visualization of pipelines in the images, additionally some materials patters proper to ...

This work deals with the location of multiple leaks in a pipeline when only the flows and pressures of the fluid at the extremes of the line are known. The key of the leaks' detector which should operate in quasi-real-time is the family F of parameterized transient models for all two leaks scenarios in the pipeline. The family F of dynamic models is obtained by considering the equivalence in the steady-state of a leak at position z eq with two leaks. This equivalence reduces the dimension of the unknown parameters' vector in the dynamic model from four to two. To estimate the specific parameters of F , an off-line identification process is suggested which minimizes the quadratic error between the pipeline data and the member of the family. Results of the leak detector with 12 scenarios offered estimation errors less than 1% in all the cases for a water pipeline of 200 [m]. This illustrates the potentiality of the parameterized transient model for the identification of multiple leaks.
