Abstract:<p>Low order streams drain a big proportion of river catchments. They are not only fed by groundwater, but may also lose water to their connected aquifers and, in turn, can contribute to a substantial fraction of groundwater recharge. In such cases, these streams are typically characterized by the coexistence of gaining and losing stream reaches. Along the bidirectional exchange flow paths large biogeochemical gradients can evolve so that the exchange zones can function as hotspots for biogeochem… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
