Hyporheic flow and transport processes: Mechanisms, models, and biogeochemical implications
Fifty years of hyporheic zone research have shown the important role played by the
hyporheic zone as an interface between groundwater and surface waters. However, it is only …

Hyporheic zone denitrification: Controls on effective reaction depth and contribution to whole‐stream mass balance
Stream denitrification is thought to be enhanced by hyporheic transport but there is little
direct evidence from the field. To investigate at a field site, we injected 15NO3−, Br …

Coupled 3‐D stream flow and hyporheic flow model under varying stream and ambient groundwater flow conditions in a pool‐riffle system
Exchange of water and solutes across the stream‐sediment interface is an important control
for biogeochemical transformations in the hyporheic zone (HZ). In this paper, we investigate …
