Research on rivers has traditionally involved concentration and flux measurements to better
understand weathering, transport and cycling of materials from land to ocean. As a relatively …

Isotopes are a potentially powerful component of monitoring and assessment programs
aimed at quantifying and mitigating alterations to environments from human activities. In …

Rivers are an important linkage in the global hydrological cycle, returning about 35% of
continental precipitation to the oceans. Rivers are also the most important source of water for …

Watershed hydrology is a field of study that concerns itself with questions of where water
goes when it rains, what flowpaths the water takes to the stream, and how long water resides …

The topic of stream flow generation has received considerable attention over the last two
decades, first in response to concern about" acid rain" and more recently in response to the …

Although early studies of streamwater residence time included the use of stable isotopes
(deuterium, oxygen‐18) and tritium, work in the last decades has largely relied on stable …

The Global Network of Isotopes in Rivers (GNIR), launched by the International Atomic
Energy Agency (IAEA) in 2007, compiles water isotope data on rivers to complement the 45 …

High-frequency measurements of solutes and isotopes (18 O and 2 H) in rainfall and
streamflow can shed important light on catchment flow pathways and travel times, but the …

Stable isotope ratios of hydrogen and oxygen have been applied to water cycle research for
over 60 years. Over the past two decades, however, new data, data compilations, and …

Determining how water sources for rivers vary over time can greatly enhance our
understanding and management of land use and climate change impacts on rivers. Because …
