Subject: Transport processes in hydraulic engineering and ecology (up to 2013)
Postgraduate studies
ECTS credits: 8,5

Remark: This subject is partially lectured by two professors: M. Jovanović i M. Ivetić.

Lectures:
1. Introductory remarks. On transport processes of scalar quantities (concentration
of chemical pollutants and river sediments, temperature, etc.) in natural watercourses,
and possibilities of mathematical modelling of such processes. Main problems in
hydraulic practice and environmental engineering.
2. Global and partial conservation laws.
3. Models of fully mixed media, equilibrium state, system response time.
4. Turbulent difussion and dispersion in natural watercourses.
5. Physical and mathematical interpretation of convection and difusion, mathematical modelling.
6. Longitudinal dispersion. Structure of mathematcial model parameters. Coefficient of the
longitudinal disersion.
7. Multidimensional models of dispersion.
8. Model calibration using analytical solutions and results of field measurements.
9. Self-purification capacity of rivers.
10. Transport capacity for bedload and suspended load.
11. Sediment transport in non-equilibrium conditions.
12. Reservoir sedimentation.
13. River sediment quality.
14. Hyperconcentrated open-channel flows.
15. Models of thermal pollution in open-channel flows. Heat exchange on boundaries.
16. Modes of nutrients-food chain interaction.
17. Eutrophication and stratification processes in lakes and reservoirs.
