While only a minimal fraction of global water resources is accessible for drinking production, their uneven distribution combined with the climate crisis impacts leads to challenges in availability. Leakage networks compounds these issues, resulting significant economic losses and environmental risks. A coherent review (a) most widely applied loss estimation techniques, (b) factors influencing them, (c) strategies resilient reduction provides comprehensive understanding current state...
Quantification of water losses (WL) in distribution networks (WDNs) is a crucial task towards the development proper strategies to reduce them. Currently, WL estimation methods rely on semi-empirical assumptions and different implementation that increase uncertainty obtained estimates. In this work, we compare effectiveness robustness two widely applied approaches found international literature: (a) balance, or top-down, approach introduced by International Water Association (IWA), (b)...
The acceleration of the climate crisis poses significant and multilayered challenges to Mediterranean societies, whose complex socio-economic structure, ecological stability, cultural heritage, are increasingly affected by expanding climatic perturbations (see e.g. Linares et al., 2020, Aurelle 2022).Due its socio-geographic heterogeneity, Greece offers a highly compelling case for an investigation social resilience adaptive capacity in response change. Along these lines, this study we...
Abstract:As all water supply systems are inherently energy-intensive, the operational efficiency of pumping infrastructure significantly affects their environmental and economic performance. Suboptimal pump configurations often result in excessive energy consumption, leading to noteworthy degradation through increased carbon emissions as well unnecessary burden. The current work aims quantify both footprint implications associated with non-optimal operations.The is assessed via a...
Rainfall erosivity is a fundamental parameter in estimating soil erosion as it quantifies the potential of raindrops to detach particles and make them available for subsequent transport by surface runoff. Erosivity depends mainly on intensity, duration, energy precipitation events, which directly affect impact surfaces The most common methods identifying erosive events emphasize short-duration, high-intensity rainfall while introducing critical thresholds characterizing such 30-minute...
Hydraulic modeling of water distribution networks (WDNs) is a vital step for all water-related professionals towards the development management practices and strategies that aim reduction losses associated financial cost environmental footprint. In current work, we develop an easy-to-implement methodology effective WDNs, which seeks to minimize computational load without undermining analysis's accuracy, using open access EPANET (Environmental Protection Agency Network Evaluation Tool)...
<p><strong>Abstract</strong></p><p>Quantification of the leakage volume in pressure management areas (PMAs) is a vital task for water agencies’ financial viability. However, currently, there no rigorous approach their parametric modeling on basis networks’ specific characteristics and inlet/operating pressures. To bridge this gap, current work focuses development probabilistic framework minimum...
Modeling of leakages in Water Distribution Networks (WDNs) is a vital task for all water related professionals and experts towards the development management practices strategies, which aim at reduction losses (leakages) associated financial cost environmental footprint. In current work we develop an integrated, theoretically founded, easily applicable probabilistic framework resilient WDNs, combines: a) set conceptually methodologically different approaches minimum night flow (MNF)...
The development and regular revision of the Greek National Flood Risk Management Plans (FRMPs) serve as direct response to guidelines introduced by Floods Directive (Directive 2007/60/EC) European Parliament Council, in order effectively mitigate manage potential risks related extreme precipitation events. current study presents a comparison between: a) Intensity-Duration-Frequency (IDF) curves obtained 2016 over Greece using Koutsoyiannis et. al (1998) methodology, b) their 2023 revised...
Partitioning of water distribution networks (WDNs) into pressure management areas (PMAs) or district metered (DMAs) is the most widely applied method for efficient and reduction real losses (leakages). Although PMA partitioning a crucial task, clustering methods are strongly affected by user-defined weighting factors that heavily affect final outcome while being associated with heavy computational loads, leading to time-consuming applications. In this work, we use hierarchical enriched...

<p>Quantification of the Water Losses (WL) components in Distribution Networks (WDNs) is a vital task towards their reduction. However, current WL estimation methods rely on semi-empirical approaches with high uncertainty levels, which usually lead to inaccurate estimates lost volume. Here, we compare probabilistic Minimum Night Flow (MNF) method introduced by Serafeim et al. (2021) Balance analysis, International Association (IWA). The strong point approach that it uses...
