Archetypes and Controls of Riverine Nutrient Export Across German Catchments
Ebeling, Pia; Kumar, Rohini; Weber, Michael; Knoll, Lukas; Fleckenstein, Jan H.; Musolff, Andreas (Water Resources Research, 2021-04-26)Elevated nutrient inputs challenge the health and functioning of aquatic ecosystems. To improve riverine water quality management, it is necessary to understand the underlying biogeochemical and physical processes, ... -
Disentangling the Impact of Catchment Heterogeneity on Nitrate Export Dynamics From Event to Long‐Term Time Scales
Winter, Carolin; Lutz, Stefanie R.; Musolff, Andreas; Kumar, Rohini; Weber, Michael; Fleckenstein, Jan H. (Water Resources Research, 2021-01-12)Defining effective measures to reduce nitrate pollution in heterogeneous mesoscale catchments remains challenging when based on concentration measurements at the outlet only. One reason for this is our limited understanding ... -
How Important is Denitrification in Riparian Zones? Combining End-Member Mixing and Isotope Modeling to Quantify Nitrate Removal from Riparian Groundwater
Lutz, Stefanie R.; Trauth, Nico; Musolff, Andreas; Van Breukelen, Boris M.; Knöller, Kay; Fleckenstein, Jan H. (Water Resources Research, 2020)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 ... -
Long‐Term Nitrate Trajectories Vary by Season in Western European Catchments
Ebeling, Pia; Dupas, Rémi; Abbott, Benjamin; Kumar, Rohini; Ehrhardt, Sophie; Fleckenstein, Jan H.; Musolff, Andreas (Global Biogeochemical Cycles, 2021-09-12)Human alteration of nutrient cycles has caused persistent and widespread degradation of water quality around the globe. In many regions, including Western Europe, elevated nitrate (NO3−) concentration in surface waters ... -
Riparian Microtopography Affects Event‐Driven Stream DOC Concentrations and DOM Quality in a Forested Headwater Catchment
Blaurock, Katharina; Garthen, Phil; da Silva, Maria P.; Beudert, Burkhard; Gilfedder, Benjamin S.; Fleckenstein, Jan H.; Peiffer, Stefan; Lechtenfeld, Oliver J.; Hopp, Luisa (Journal of Geophysical Research: Biogeosciences, 2022-12-21)The transport of dissolved organic carbon (DOC) from the soils to inland waters plays an important role in the global carbon cycle. Widespread increases in DOC concentrations have been observed in surface waters over the ... -
Seasonal and short‐term controls of riparian oxygen dynamics and the implications for redox processes
Nogueira, Guilherme E. H.; Schmidt, Christian; Trauth, Nico; Fleckenstein, Jan H. (Hydrological Processes, 2021-02-23)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 ...
