Language:

English

Summary

Focus is on lakes, rivers and reservoirs as aquatic systems. Specific is the quantitative description / analyse of physical, biological, biogeochemical and sedimentological processes and interactions. The goal is to understand the relevant processes (focus on water quality) from a practical point.

Content

The themes comprise: themes

1. Water, nutrient and salt balances (critical loads, one-box models, flux analysis)

2. Physical environment (density, stratification, mixing, advection, diffusion, heat fluxes, wind forcing and climate effects)

3. Mixing regimes (boundary layers, stratified turbulence, double diffusion)

4. Geochemical environment (photosynthesis, remineralisation, sedimentation, biogeochemical elemental cycling, particles, oxygen depletion; anaerobic processes)

5. Biological environment (photosynthesis (light, nutrients), phytoplankton, zooplankton, remineralisation),

6. Sedimentation processes and particle distributions

7. System analysis combining advection, diffusion, and reactions

8. Limnological research techniques

9. Environmental issues (eutrophication, pollution, WRM).

 

 

Keywords

Natural water resources, aquatic system production, biogeochemical cycling, water quality, plankton, water layers

Learning Prerequisites

Required courses

BSc completed. Basic courses in hydrology, physics and mathematics; interest in system analysis and quantitative formulations

Recommended courses

System analysis, hydrology, aquatic geochemistry, aquatic biology.

Important concepts to start the course

Numerical quantification of processes in stratified waters

Aquatic system analysis

Linking physical boundary conditions to quantitative flux estimates of matter and momentum

Learning Outcomes

By the end of the course, the student must be able to:

Teaching methods

2 hrs per week of instructions (basic knowledge and concepts) and 2 hrs per week of problem solving. Problem solving will be based on real data and practical questions. The goal is to learn the real lake- and reservoir-processes by addressing concrete quantitative questions which can be generalized. Motivation is given by scientific as well as practical engineering problems.

Expected student activities

One set of problems per week of homework, which will be digested and generalized in class. The students are expected not only to solve the problem as homework, but also to present and discuss the solutions in class.

Assessment methods

Feedback on the problem solving each week by the assistants. Final oral exam.

Supervision

Assistants Yes

Resources

Bibliography

Weekly classnotes (aboit 200 pages in total) will be provided and a list of further readings
