Archetypes and Controls of Riverine Nutrient Export Across German Catchments
(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, ... -
Comparison of environmental tracers including organic micropollutants as groundwater exfiltration indicators into a small river of a karstic catchment
(Hydrological Processes, 2020-09-29)Understanding groundwater–surface water (GW–SW) interactions is vital for water management in karstic catchments due to its impact on water quality. The objective of this study was to evaluate and compare the applicability ... -
Disentangling the Impact of Catchment Heterogeneity on Nitrate Export Dynamics From Event to Long‐Term Time Scales
(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 ... -
Field Tracer Tests to Evaluate Transport Properties of Tryptophan and Humic Acid in Karst
(Groundwater, 2020)The monitoring of water quality, especially of karst springs, requires methods for rapidly estimating and quantifying parameters that indicate contamination. In the last few years, fluorescence-based measurements of ... -
Long‐Term Nitrate Trajectories Vary by Season in Western European Catchments
(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 ... -
Response of large benthic foraminifera to climate and local changes: Implications for future carbonate production
(Sedimentology, 2021-05-18)Large benthic foraminifera are major carbonate components in tropical carbonate platforms, important carbonate producers, stratigraphic tools and powerful bioindicators (proxies) of environmental change. The application ... -
Revisiting global trends in freshwater insect biodiversity: A reply
(Wiley Interdisciplinary Reviews: Water, 2020-12-31)Jähnig et al. make some useful points regarding the conclusions that can be drawn from our meta‐analysis; however, some issues require clarification. First, we never suggested that there was a globally increasing trend of ... -
Spatial and Temporal Variability in Concentration‐Discharge Relationships at the Event Scale
(Water Resources Research, 2021-10-13)The analysis of concentration‐discharge (C‐Q) relationships from low‐frequency observations is commonly used to assess solute sources, mobilization, and reactive transport processes at the catchment scale. High‐frequency ... -
The effect of stream shading on the inflow characteristics in a downstream reservoir
(River Research and Applications, 2021-06-14)In thermally stratified reservoirs, inflows form density currents according to the interplay between inflow temperature and reservoir stratification. The temperature of inflowing water is affected by catchment properties, ...
