• Physics-informed Lucas-Washburn equation captures nanoscale capillary imbibition. • Coupled interfacial and thermal effects integrated through a scaling factor f . • Model validated across minerals and experiments with R 2 up to 0.95. The classical Lucas-Washburn (LW) equation fails to accurately describe capillary imbibition phenomena in soil nanopores, where nanoconfinement, temperature, and …

• A root water uptake model with waterlogging effects on root hydraulics was built. • The model effectively estimated plant hydraulic conductance and transpiration. • The model improved estimation accuracy, especially after prolonged waterlogging. • Transpiration was controlled by root hydraulics under moderate evaporative demand. In humid regions, intensive and intermittent precipitation has inc…

• A method to track rainfall contribution in a conceptual rainfall-runoff model. • Wetter catchments respond more to short-term rainfall than drier catchments. • Modelled runoff increasingly depends on multi-annual rainfall during extended dry periods. • The method provides insight into the flow generation mechanism. This paper presents a novel method to analyse how conceptual rainfall-runoff mod…

• Optimal scaling 5.5–8.4% K −1 varies with event duration and return period. • High-elevation basins show strong CPM–scaling agreement; lowlands weak links. • Seasonal shifts degrade scaling reliability, especially for longer-duration storms. • Event-based temperature outperforms mean annual temperature in T-P scaling. Quantifying future changes in sub-daily extreme precipitation in mountainous …
