Exercise

13 weeks, 2 hours/week, compulsory

Syllabus

1. Assignment of the sediment study of a river reach. Underlying data for the study. 2. Model of the uniform flow of water. 3. Model of the uniform transport of sediments: incipient motion of sediments, transport curve. 4. Model of the uniform transport of sediments: effective discharge, average annual discharge of sediments. 5. 1D model of the nonuniform flow of water. 6. 1D model of the nonuniform transport of sediments. 7. 1D model of the long-term nonuniform transport of sediments before construction of the dam. 8. 1D model of the long-term nonuniform transport of sediments after construction of the dam. 9. Calculation of the deposition of sediments in reservoir by empirically determined trap efficiency curves. 10. Comparison of the annual transport of sediments and the sediment deposition in reservoir by various methods. 11. Report of the sediment study of river reach. 12. Presentation of the sediment study of river reach. 13. Control of study duties. Credit.
