The paper deals with the determination of the settling velocity of phosphorus in lakes and reservoirs. The main approaches to estimate the phosphorus loss in aquatic ecosystems are presented. A case study of a lake situated in Berlin, Germany is discussed. The results show that in aerated lakes the values of the settling velocity of phosphorus can be much higher than currently assumed in the literature.
