Carbon export in boreal catchments depends on the landscape setting and differs for snowmelt and rainfall events.
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.
Radioactive isotope tracers can be used to determine the relationship between the ages of water that is stored in soil and bedrock, water in streams, and the water used by vegetation.
New research challenges long-held ideas about the path of subsurface water from hillslopes to streams.
Citizen scientists keep a watchful eye on the world’s streams, catching intermittent streams in action and filling data gaps to construct a more complete hydrologic picture.
