Simulation of a Biogeochemical Model in Different Lakes
Simulation Biogeochemical Model Different Lakes
2009/10/22
Eutrophication, caused by nutrients leached from soil and emitted from point
sources, is a well-known problem in many Swedish lakes. There are several
countermeasures that can be used to reduce eutr...
