The latest issue of the scientific journal Sustainability published an article by our colleagues – Artur Zajkowski, Łukasz Wysocki and Piotr Tuz, written in cooperation with prof. Izabela Bartkowska from the Białystok University of Technology.
The publication analyzes how leaks are detected in rural and urban-rural water systems through hydraulic modeling and sensitivity analysis.
The authors examined two different real-world network models to evaluate real and simulated leak scenarios varying in location and magnitude. They tested a different method of detecting leaks, using measurements of the flow from hydrants. Additionally, they evaluated the performance of various statistical measures—such as correlation, angular proximity, Euclidean distance, Manhattan distance, Chebyshev distance, cosine similarity, and Spearman correlation—to determine their effectiveness in detecting leaks.
Various methods for identifying potential leaks were investigated and compared, either by selecting a single potential leak based on similarity measures, or by identifying a group of potential leaks to mark leak hotspots. Density-based spatial clustering of noisy applications was used to estimate the number of potential clusters of potential leaks.
The study results contribute to the optimization of leak detection strategies in water supply networks, especially in rural areas, where detection is difficult due to sparse measurement data sets, budget and operational constraints.
