Decoding urbanization effects on the water cycle: a multi-faceted analysis of balance, magnitude, and memory Open
The effects of urbanization on water cycle dynamics are a global concern as cities expand worldwide. This study aims to investigate these effects on Korea's largest campus catchment, Seoul National University Gwanak campus (∼2.9 km2), refl…

Nutrient loading and stream order shape benthic and pelagic spring algal biomass in a large, temperate river basin (Elbe River) Open
Eutrophication persists in many freshwater systems despite extensive efforts to control nutrient emissions from point and diffuse sources. While intensely studied at local or regional scales, the joint response of benthic and pelagic algae…
