1. Properties of rivers and fluvial processes. Systems and scales in regional geomorphology, classification of channel types and
river patterns.
2. River variability and complexity, geomorphic assessment of rivers; controls of river morphology and behaviour; fixed and
variable local controls.
3. Stream sediment and modes of its transport - classification of sediment, sediment sampling, incipient transport, bed forms,
transport regimes and their thresholds
4. Channel resistance - effects of boundary roughness, vegetation, bed forms, sediment transport. Internal structure of flow in
mobile-bed channels.
5. Equilibrium transport of bed load, suspended load and total load - hydrodynamic, friction, and transport formulae.
6. Transport of sediment out of equilibrium - short-term morphodynamic responses of a mobile-bed river.
7. Transport of sediment out of equilibrium - long-term morphodynamic responses of a mobile-bed river.
8. Principles of mathematical modelling of flow with transport of sediment over mobile bed. 1D and 2D examples of depth
averaged model solutions.
9. Physical models with mobile bed. Dimensional analysis, model similitude principles.
10. Mountain stream morphology - intense bed load and debris flow, kinetic theory based modelling.
11. Stability of stream thread.
12. Geomorphic analysis of river channel changes due to scouring and bank failure (bank retreat), effects of vegetation, LWD
and river ice on channel morphology.
13. Modelling approaches to the ecology of fluvial system and river chemistry. River pollution and mixing zones. |
