Previously regarded as the passive drains of watersheds, over the past 50 years, rivers have
progressively been recognized as being actively connected with off‐channel environments …

Abstract Models test our understanding of processes and can reach beyond the spatial and
temporal scales of measurements. Multi-component Reactive Transport Models (RTMs) …

In this chapter, the authors aim to uncover the organizational principles–the main drivers
and controls, and their interactions and feedbacks–that determine the development and …

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 …

In this chapter, the authors provide a comprehensive analysis and synthesis of the
interactions between important drivers and controls of hyporheic exchange and …

Global quantitative estimations of ecosystem functions are vital. Among those, ecosystem
respiration and photosynthesis contribute to carbon cycling and energy flow to food webs …

Shallow benthic biolayers at the top of the streambed are believed to be places of enhanced
biogeochemical turnover within the hyporheic zone. They can be investigated by reactive …

The use of smart tracers to study hydrologic systems is becoming more widespread. Smart
tracers are compounds that irreversibly react in the presence of a process or condition under …

Greenhouse gas (GHG) emissions of carbon dioxide (CO2) and methane (CH4) from
streambeds are currently understudied. There is a paucity of research exploring organic …

Abstract Groundwater–surface-water (GW-SW) interactions in streams are difficult to quantify
because of heterogeneity in hydraulic and reactive processes across a range of spatial and …
