Groundwater flow and contamination studies

Losses of non-revenue water (NRW) due to undetected leaks threaten the sustainability and operational efficiency of water distribution systems. This study presents an adaptive real-time DBSCAN-Leak algorithm. This algorithm enhances the conventional Density-Based Spatial Clustering of Applications with Noise (DBSCAN)…

Groundwater recharge is critical because it restores the underground aquifers that supply billions of people. Over-abstraction of groundwater without recharge can lead to falling water tables, land subsidence and long-term ecological damage. As natural recharge is slow in many areas, particularly in arid and semi-arid…

This paper investigates a pollution model for a closed system consisting of three physically interconnected lakes. The pollutant source enters the first lake, while the exchange of contaminants among the lakes is described by a coupled system of first-order differential equations. To obtain accurate numerical solution…

Abstract Operation of eccentric wells in a circular island unconfined aquifer under steady state flow conditions was addressed in this study by comparing the results of experimental, analytical and developed numerical models. MODFLOW was used in the developed numerical models. The results include simulations of variou…

Dynamic management of urban drainage networks necessitates the integration of cyber-physical systems to overcome the limitations of static design approaches. This study presents a universal technical handbook that combines the topological integrity of AutoCAD Civil 3D with the full dynamic modeling capacity of the Sew…

The assessment of groundwater vulnerability to pollution is essential for identifying and protecting zones affected by nitrate contamination due to intensive agricultural activities. Groundwater quality monitoring requires sample collection and laboratory analysis, making it an expensive process. It is essential to ma…
