Identifying preferential paths for groundwater flow is one of the basics understanding aquifer systems. Shallow free-surface aquifers often have directions (locally) similar to those their surface counterparts, especially if and bodies are directly connected. This work proposes a novel simple framework improve identification Preferential Groundwater Networks in aquifers. possible by proposing quantile mapping procedure borrowed from stochastic hydrology, usually employed adjust rainfall simulations (for example, achieved via climate models) upon available gauge-based data. well-known applied redistribute bottom elevation real case study Lombardy, Northern Italy.

This study was conducted to determine potential groundwater storage areas in the semi-arid Oltu Basin northeastern Turkey. The of basin analyzed by evaluating eight geographical factors: lithology, linear density, soil depth, land use, precipitation, geomorphology, slope, and drainage density. These factors were classified weighted using remote sensing, information systems (GIS), analytic hierarchy process (AHP). obtained data modeled ArcGIS software, a map created. results show that there is high close stream bed, while low mountainous steeply sloped regions. provides significant findings for sustainable water resource management region future resources planning.

Debris flows, consisting of water–sediment mixtures that travel rapidly along channels, often carry materials ranging from fine sediments, such as clay or silt, to large boulders, resulting in significant impacts on lives and infrastructure. Accurate estimation the debris-flow behavior is crucial for establishing effective mitigation strategies. However, dynamic entrainment process complicates simulations because it significantly affects flow characteristics, including velocity, depth, sediment concentration. In this study, we analyzed effects debris using two one-dimensional models a event occurred 2011 Seoul, Republic Korea. The results show improves accuracy simulation. Moreover, scheme dealing with entrained governing equations important reproducing characteristics. These findings highlight necessity simulation, implications enhancing hazard
