Magdalena Bieroza

Magdalena Bieroza
I am a catchment hydrologist, biogeochemist and computer scientist by profession. I am interested in catchment- and reach-scale nutrient and organic matter dynamics in agricultural catchments. I am particularly interested in high-temporal resolution stream biogeochemical responses and monitoring using on-line in situ sensors.



1. Phosphorus Mitigation At Headwater Catchment-Scale: Are Hydrological Extremes And Legacy Phosphorus Overriding The Management Efforts? A new paper, currently in review with the Journal of Environmental Quality. We show that individual mitigation measures are reducing nutrient and sediment concentrations but prolonged drought and resuspension of sediments exacerbate phosphorus and sediment stream export. 

2. EGU presentation Phosphorus mitigation at headwater catchment-scale: is increased hydrological flashiness overriding the management efforts? 08 Apr 2019, 16:15, Room 2.95. 

3. EGU Monday with Advancing understanding of hydrochemical and ecological processes controlling fate of natural organic matter, nutrients and pollutants in freshwater and engineered systems using state-of-the-art methods.
