Eutrophication (EU)
Strong Tool for Environmental Analyses
The eutrophication (EU) module, developed by DHI Water & Environment, is an advanced tool which has been used in a long
range of contexts for calculating the consequences of human impacts on the environment.
Model Description
The model describes the growth of phytoplankton, zooplankton, benthic vegetation and oxygen conditions as a consequence of
BOD loading, available nutrients and factors such as incident light intensity, water temperature and hydraulic conditions.
The biological and chemical system described in the EU model consists of a network of coupled processes where
changes in one component could influence all the other variables depending on the biological reaction. The state variables and processes included in the system are:
- Phytoplankton carbon
- Phytoplankton nitrogen
- Phytoplankton phosphorus
- Chlorophyll concentration
- Zooplankton carbon
- Detritus carbon
- Detritus nitrogen
- Detritus phosphorus
- Inorganic nitrogen
- Inorganic phosphorus
- Dissolved oxygen
- Benthic vegetation
