Due to increased water density and viscosity, the falling organic particles are trapped in the metalimnion. The easily oxidizable material is decomposed in this layer causing severe oxygen depletions. The orthophosphate phosphorus does not ea

The models ranged from simple zero and first order order net exchange of phosphorus to complex multicompartment models which included oxygen metabolism effects. Eight models were tested for time response and steady state conditions at various hydraulic loadings. Time response, stability

As eutrophy is the normal situation in surface waters in the low parts of The Netherlands, enrichment by inorganic nutrients leads to hypertrophy; enrichment by organic substances leads to saproby. Retention of organic matter in waste water treatment plants reduces saproby, but hyp

The influence of short-term variations on the nutrient input, external as well as internal, will be discussed from a lake recovery study in Sweden carried out in 30 lakes..The external input of nutrients to a lake is often calculated on an annual basis but may be misleading a

Evidence is given to show that in addition to the thesis being correct intuitively, it can be supported by field experiments and by observations even on such well-known lakes as L. Washington, L. Norrviken, L. Trummen, and L. Mendota. Emphasis is on the roles of herbivorous
