Numerical Simulation of Flow Maldistribution at Pipeline Junctions in Water Distribution Networks Open
The uneven distribution of flow in water distribution networks (WDNs) can cause inefficient flows and pressure imbalances as well as degraded water quality in areas where demand is higher than the networks’ design limit. In this study, two…
Adapting to the Escalating Climate Crisis in the Mediterranean Region: The case of Greece Open
The acceleration of the climate crisis poses significant and multilayered challenges to Mediterranean societies, whose complex socio-economic structure, ecological stability, and cultural heritage, are increasingly affected by expanding cl…
Refining Rainfall Erosivity Estimation: Methodological improvements towards more accurate soil erosion assessments Open
Rainfall erosivity is a fundamental parameter in estimating soil erosion as it quantifies the potential of raindrops to detach soil particles and make them available for subsequent transport by surface runoff. Erosivity depends mainly on t…
Assessing the Environmental Footprint of Suboptimal Pump Configurations in Water Distribution Systems Open
As all water supply systems are inherently energy-intensive, the operational efficiency of the pumping infrastructure significantly affects their environmental and economic performance. Suboptimal pump configurations often result in excess…
Leakages in Water Distribution Networks: Estimation Methods, Influential Factors, and Mitigation Strategies—A Comprehensive Review Open
While only a minimal fraction of global water resources is accessible for drinking water production, their uneven distribution combined with the climate crisis impacts leads to challenges in water availability. Leakage in water distributio…
Assessing the Evolution of Intensity – Duration – Frequency Curves over Greece: A Comparative Study between 2016 and 2023 Open
The development and regular revision of the Greek National Flood Risk Management Plans (FRMPs) serve as direct response to the guidelines introduced by the Floods Directive (Directive 2007/60/EC) of the European Parliament and of the Counc…
Towards More Efficient Hydraulic Modeling of Water Distribution Networks Using the EPANET Software Engine Open
Hydraulic modeling of water distribution networks (WDNs) is a vital step for all water-related professionals towards the development of management practices and strategies that aim for the reduction of water losses and the associated finan…
Probabilistic modelling of water distribution networks and resilient reduction of leakages: Large scale application to the city of Patras in western Greece Open
Modeling of leakages in Water Distribution Networks (WDNs) is a vital task for all water related professionals and experts towards the development of management practices and strategies, which aim at the reduction of water losses (leakages…
Combining Statistical Clustering with Hydraulic Modeling for Resilient Reduction of Water Losses in Water Distribution Networks: Large Scale Application Study in the City of Patras in Western Greece Open
Partitioning of water distribution networks (WDNs) into pressure management areas (PMAs) or district metered areas (DMAs) is the most widely applied method for the efficient management and reduction of real losses (leakages). Although PMA …
Parametric model for probabilistic estimation of water losses in water distribution networks: A large scale real world application to the city of Patras in western Greece Open
AbstractQuantification of the leakage volume in pressure management areas (PMAs) is a vital task for water agencies financial viability. However, currently, there is no rigorous approach for their parametric modeling on the basis of networ…
Probabilistic water losses estimation in water distribution networks and comparison with the top down - water balance approach: A large-scale application to the city center of Patras in western Greece Open
Quantification of the Water Losses (WL) components in Water 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 …
Probabilistic Minimum Night Flow Estimation in Water Distribution Networks and Comparison with the Water Balance Approach: Large-Scale Application to the City Center of Patras in Western Greece Open
Quantification of water losses (WL) in water distribution networks (WDNs) is a crucial task towards the development of proper strategies to reduce them. Currently, WL estimation methods rely on semi-empirical assumptions and different impl…
Practical Estimation of Minimum Night Flow in Water Distribution Networks: Large-scale Application to the City of Patras in Western Greece Open
AbstractIn the present work we develop and test a non-parametric statistical methodology to obtain point estimates of Minimum Night Flow (MNF) in Water Distribution Networks (WDNs). The methodology constitutes a simplified version of the a…
