Repeating a famous hillslope experiment after 55 years shows that soil properties can change within several decades and highlights the importance of a leaky boundary for hillslope drainage.

New Isotope Model Predicts Denitrification from Riparian Zones
A new model quantifies the relative contributions of denitrification and other processes of nitrogen uptake, such as by plants, from groundwater in riparian areas around streams.
Hydropower and Bugs
Alpine hydropower plants commonly flush sediment that accumulates at intakes, but the associated rapid rise in discharge, turbidity, and streambed instability put aquatic insects at risk.
Reconstructing Natural Streamflow at Unprecedented Resolution
A new research effort has mapped 35 years of naturalized streamflow for 2.94 million river reaches worldwide: an invaluable dataset for hydrology, biogeochemistry, ecology, and remote sensing.
Groundwater Drawn Downward After Kumamoto Quake
A unique set of high-frequency groundwater level monitoring reveals a loss of approximately ten million cubic meters of groundwater after a major earthquake.
Earthquakes Shake Up Groundwater Systems
Increased permeability temporarily boosts water flow.
Capturing Snowmelt Patterns from Cloudy Satellite Images
A new modeling strategy could improve streamflow predictions in places where mountain snow is a critical source of water.
Treating Colloids as Clusters Better Predicts Their Behavior
New research suggests that an accurate prediction of colloidal particle mobilization in the environment should account for the effect of clustering.
Restoring Natural Fire Regimes Can Yield More Water Downstream
Research in Yosemite National Park offers a new benchmark for understanding water balance changes in a mountainous basin 4 decades after its natural wildfire regime was reestablished.
Forested Streams May Warm More Than Observations Predict
Understanding how temperatures of cold-water streams respond to global warming could help clarify the impacts of climate change on aquatic ecosystems.
