“…A function of many complex systems concerns provision of one or more fundamental services to support health and well-being, e.g., water distribution across a landscape through green infrastructure (re)development. A functional performance approach takes a step past a condition-based approach such that characteristics of conditions support delivery of a functional service level [16]. Functional service has become so important that some researchers characterize functional performance in terms of critical functionality [8,17], wherein the functional performance of certain elements within systems, and certain systems within interconnected systems, are more important to delivery of service than other functions.…”

This paper synthesizes vulnerability, risk, resilience, and sustainability (VRRS) in a way that can be used for decision evaluations about sustainable systems, whether such systems are called coupled natural–human systems, social–ecological systems, coupled human–environment systems, and/or hazards influencing global environmental change, all considered geospatial open systems. Evaluations of V-R-R-S as separate concepts for complex decision problems are important, but more insightful when synthesized for improving integrated decision priorities based on trade-offs of V-R-R-S objectives. A synthesis concept, called VRRSability, provides an overarching perspective that elucidates Tier 2 of a previously developed four-tier framework for organizing measurement-informed ontology and epistemology for sustainability information representation (MOESIR). The new synthesis deepens the MOESIR framework to address VRRSability information representation and clarifies the Tier 2 layer of abstraction. This VRRSability synthesis, composed of 13 components (several with sub-components), offers a controlled vocabulary as the basis of a conceptual framework for organizing workflow assessment and intervention strategies as part of geoinformation decision support software. Researchers, practitioners, and machine learning algorithms can use the vocabulary results for characterizing functional performance relationships between elements of geospatial open systems and the computing technology systems used for evaluating them within a context of complex sustainable systems.

“…Thus, level of leakage of clean water infrastructure network currently occurring still has great potential for reduction. However, reduction of water loss entails costs for investment as well as for water loss reduction operation [16]. In fact, management of drinking water providers must have a degree of limitation in providing costs [17].…”

This study aimed at determining Infrastructure Leakage Index (ILI) supported by Geographic Information System (GIS) to facilitate strategy determination, map problems, and determine potential revenue for actions to solve leakage realistically, effectively and efficiently. Economic analysis was carried out to determine investment feasibility of corrective actions for leakage of clean water network infrastructure. More importantly, variables in this study were obtained from literature review. Primary and secondary data were then collected and analyzed statistically, and other economic analysis tools were also used. This study used a quantitative method with a population of 11 (eleven) service zones involving 35 leaders, executors and staff of leakage team. All populations of service zone were taken as research sample, while for leakage team, sample was taken using Slovin formula which obtained 32 respondents. Questionnaires were distributed to find the main affecting factors using AHP (Analytical Hierarchy Process) method with the help of Expert Choice software Results of this study indicated that there were basically five main factors causing water loss due to infrastructure leakage. Handling infrastructure leakage could reduce rate of physical water leakage by 48.5% (from 11.38% to 5.86%) of the total physical losses per year. In addition, return on investment was obtained in year 3, while profits were earned in year 4.

“…These could include cross-border inter-sectorial effects resulting from the interdependent relationships between interconnected infrastructures (e.g., decommissioning of a portion of the drinking water network, making it impossible for fire-fighters to intervene in the event of a disaster, etc.). Some innovative technology for the design, rehabilitation or modernization of systems infrastructure in order to also includes a way to increase the seismic resilience of vital plant infrastructure is urgently required, given the risks of earthquakes associated with pipeline systems: loss of integrity/tightness of all or part of the subcomponents [7]. This would lead to disaster risks, with a major impact on civil protection, on national security or on the security of major objectives.…”

Experimental Study on the Behaviour of Seismic Actions on a Flexible Glass-Reinforced Plastic Structure Used in Water Transport Pipes

This article presents the experimental results obtained by the testing an experimental model of water distribution which is flexible and above-head mounted on a seismic platform, and their validation in a theoretical manner, but also by the Finite Element Method, using the ANSYS simulation program. This type of system shown by the experimental model is desired to be used in practice not only in seismic areas, but also in the areas of heavy road transport, landslides, etc. thorugh the use thereof in the most stressed points of the network (hearth entry/exit, before/after an elbow, etc.) but also on long routes, at optimal distances. The results achieved are related to glass- reinforced plastic (GRP) pipes with a nominal diameter DN = 250 mm, but conclusions may be drawn starting from these to help future research where the mass of the earth is desired to be taken into account. The present results are comprehensive for buried pipes operated dynamically or seismically at low-medium intensity, as this type of earthquake occurs more and more often in Europe. The experimental tests in this article do not have the characteristics necessary for a high intensity seismic action (above 5° Richter).
