Abstract: | Cumulative frequency distributions of ammonium concentrations in Swiss rivers demonstrate that today ammonium standards are
exceeded in relatively small rivers only. A predictive, mechanistic nitrification model for rivers is developed and discussed.
The model is applicable in rivers with small hydraulic radii (<1 m) and reasonable flow velocities (∼1m/sec). In a case study
for the river Glatt the model is applied (verified) and used as a predictive tool.
