Effect of Mid‐Channel Bar Geometry on Hyporheic Exchange Open
Hyporheic exchange has been shown to provide essential ecosystem functions such as biogeochemical opportunities for nutrient processing. Hyporheic exchange flux (HEF) and residence time (RT) in the hyporheic zone are highly influenced by t…

Seasonal and short‐term controls of riparian oxygen dynamics and the implications for redox processes Open
Riparian zones are highly‐dynamic transition zones between surface water (SW) and groundwater (GW) and function as key biogeochemical‐reactors for solutes transitioning between both compartments. Infiltration of SW rich in dissolved oxygen…

How Important is Denitrification in Riparian Zones? Combining End‐Member Mixing and Isotope Modeling to Quantify Nitrate Removal from Riparian Groundwater Open
Riparian zones are important buffer zones for streams as they are hotspots of nitrate transformation and removal in agricultural catchments. However, mixing of water from different sources and various transformation processes can complicat…

Sources and variability of CO<sub>2</sub> in a prealpine stream gravel bar Open
Gravel bars (GBs) contribute to carbon dioxide (CO 2 ) emissions from stream corridors, with CO 2 concentrations and emissions dependent on prevailing hydraulic, biochemical, and physicochemical conditions. We investigated CO 2 concentrati…

Modeling the Impact of Stream Discharge Events on Riparian Solute Dynamics Open
The biogeochemical composition of stream water and the surrounding riparian water is mainly defined by the exchange of water and solutes between the stream and the riparian zone. Short‐term fluctuations in near stream hydraulic head gradie…

Estimating time‐variable aerobic respiration in the streambed by combining electrical conductivity and dissolved oxygen time series Open
Aerobic respiration is an important component of in‐stream metabolism. The larger part occurs in the streambed, where it is difficult to directly determine actual respiration rates. Existing methods for determining respiration are based on…

“Untangling Hyporheic Residence time Distributions and Whole Stream” “Metabolism Using a Hydrological Process Model” Open
The interaction of the water residence time (RT) in hyporheic sediments with the sediment metabolic rates is believed to be a key factor controlling whole stream metabolism. However, due to the methodological difficulties, there is little …
