Short summary

During a flood in the Elbe in June 2013, a unique co-occurrence of ammonium, nitrite and nitrate in the water column was found. SPM and nutrient concentrations as well as isotopes were analysed. We calculated an isotope effect ¹⁵ε of −10.0 ± 0.1 ‰ during net nitrite and ¹⁵ε of −4.0 ± 0.1 ‰ and ¹⁸ε of −5.3 ± 0.1 ‰ during net nitrate consumption. A simple box-model calculation results in combined riparian denitrification and 22 to 36 % nitrification.
