2. Objectives and learning outcomes
2.1 Objectives
The course offers an introduction to lake limnology, focussing on the governing physical processes in shallow lakes, but also covering water quality, ecology and aspects of lake management. General topics:
- micrometeorology: wind and surface shear
- hydrodynamics: wind-induced water motions: surface setup, currents, surface waves
- thermodynamics: energy budget, stratification, heat fluxes
- sediment dynamics: bed shear, sediment transport
- hydrology: water balance
- water quality and ecology
2.2 Learning outcomes
Upon successful completion of this subject, the student:
A. Knowledge
- You will understand the physical processes governing water quality and ecology of shallow lakes.
B. Skills
C. Attitudes
D. Autonomy and Responsibility
2.3 Methods
Weekly lectures.
