Learning Outcomes

After the successful completion of the module the students: Understand the mechanisms underlying phytoplankton ecology in surface waters, including transport growth and death, and toxin production; and can represent them quantitatively using mathematical modeling. - Understand basic eutrophication processes - Understand the modeling process, including selecting the optimal model and complexity, calibrating to field observations, applying and documenting/presenting the model - Can set up and solve differential mass balance equations using various techniques - Master basic principles of eutrophication modeling in lakes, rivers and estuaries - Have experience in setting up and applying off-the-shelf water quality modeling programs The module´ s qualification profile is: 40% knowledge and understanding, 20% development and design, 20% research and evaluation, 20% application in practice


The following topics will be covered: • Basic mechanisms through which environmental water quality becomes degraded by nutrients (eutrophication). • Transport processes in rivers, lakes and estuaries. • Kinetic processes governing phytoplankton ecology, including photosynthesis, respiration, grazing and others, and their mathematical description. • Mass balance equations and their analytical and numerical solutions. • Setup and parameterization of models for surface water systems.
