Optimal nutrient pollution monitoring and management in catchments requires an in-depth understanding of spatial and temporal factors controlling nutrient dynamics. Such an understanding can potentially be obtained by analysing stream concentration

Use of high spatial resolution nitrogen attenuation mapping in groundwater and surface waters for planning how to reach nitrogen reduction goals in 3rd River Basin Management Plans: Hjarbæk coastal catchment, Denmark
Autor: Jørgen Windolf, Henrik Tornbjerg, Søren Larsen, Brian Kronvang
Publikováno v: Windolf, J, Tornbjerg, H, Larsen, S E & Kronvang, B 2023, ' Use of high spatial resolution nitrogen attenuation mapping in groundwater and surface waters for planning how to reach nitrogen reduction goals in 3rd River Basin Management Plans: Hjarbæk coastal catchment, Denmark ', EGU General Assembly 2023, Vienna, Austria, 23/04/2023-28/04/2023 .
The requirements under the present River Basin Management Plans (RBMP) for the EU Water Framework Directive (WFD) are to reduce the total nitrogen (TN) loadings to the Hjarbæk Estuary in Denmark from the present (2015-2019) annual loading of 1900 to

Assessment of agricultural nitrogen pressures and legacies in Denmar
Autor: Jørgen Windolf, Henrik Tornbjerg, Gitte Blicher-Mathiesen, Brian Kronvang
The links between nitrate-nitrogen (N) leaching from agricultural fields and N measured in streams can in general terms be divided in two pathways: groundwater and a more surface-near transport (e.g. tile drains). The former with a typical slower hyd

Publikováno v: Wu, N, Thodsen, H, Andersen, H E, Tornbjerg, H, Baattrup-Pedersen, A & Riis, T 2019, ' Flow regimes filter species traits of benthic diatom communities and modify the functional features of lowland streams-a nationwide scale study ', Science of the Total Environment, vol. 651, no. 1, pp. 357-366 . https://doi.org/10.1016/j.scitotenv.2018.09.210
Changes in land use, climate and flow diversion are key drivers of river flow regime change that may eventually affect freshwater biodiversity and ecosystem functions. However, our knowledge is limited on how the functional features of stream organis

Modeling annual diffuse phosphorus concentrations in Danish mini-catchments
Autor: Ane Kjeldgaard, Brian Kronvang, Henrik Tornbjerg, Søren Ejling Larsen, Jørgen Windolf, Hans Thodsen
Intensive monitoring data from the Danish National Monitoring programme (NOVANA) from 24 smaller catchments (mean: 14 km2) was used in a two layer cross-validation to establish a model for the annual diffuse phosphorus (P) flow-weighted concentration

Nitrogen concentrations in flow separated river water
Autor: Hans Thodsen, Henrik Tornbjerg, Jørgen Windolf, Peter Sørensen, Brian Kronvang
Nitrogen (N) loads and concentrations have been successfully reduced in most Danish streams during the last 30 years. Thereby also reducing the impact of the main driver of marine eutrophication in Danish coastal waters. However, the trend in N-loads
