| Contents Notes | A system of mass balance models for lakes was developed which included different hydraulic and kenetic descriptions. The hydraulic descriptions were the continuously sturred tank reactor (CSTR) and two modifications of the plug flow reactor (PFR), one with no additional input and one with additional input. A combination of CSTR and PFR was also treated. First and second order sedimentation kenetics were included in the model modifications and both voluminal and areal versions were considered. In voluminal versions the sedimentation is assumed to be proportional to volume, in areal versions to surface area. The models were tested against phosphorus data of Lakes Haukivesi and Paijanne, both situated in central Finland. |
