- Characterization of the fluvial environment
- Sedimentology: erosion criteria and sediment transport
- Fluvial morphology
At the end of this learning unit, the student is able to :
Contribution to the acquisition and evaluation of the following learning outcomes of the programme in civil engineering: AA1.1, AA1.2, AA1.3, AA2.1, AA2.2, AA2.3, AA3.1, AA3.3, AA5.2, AA5.3, AA5.4, AA5.5, AA5.6, AA6.1, AA6.2, AA6.3
More specifically, at the end of the course, the student will be able to:
· Definitions, general river morphology, bedforms
- Modes of sediment transport
Non-dimensional variables of sedimentology
- Velocity distribution, mean velocity, shear velocity
- Dimensional analyssis and characteristic numbers
Threshold for erosion of sediment bed
- Velocity criterion and river equilibrium profile
- Shear stress criterion : Shields and van Rijn diagrams
Bed-load sediment transport
- Transport principles of du Boys
- Analysis of Meyer-Peter and Müller
- Other current approaches (Einstein, Bagnold, etc.)
Suspended load sediment transport
- Transport équations
- Equilibrium concentration profile (theory of Vanoni'Rouse)
- Suspended load (Einstein's integration)
- Practical formulae : regime theories
- Bank stability, stable cross-section shape
- Morphological response to river training works
- Helical flow in meanders
- Principles : Fargue's laws and rules
- Local works : surface panels, bandalling, bottom panels, bottom sills, bank protection
- River works : banks, longitudinal dikes, groynes, sills
Due to the COVID-19 crisis, the information in this section is particularly likely to change.
Numerous examples are given, from the litterature or based on the teacher's experience.
Due to the COVID-19 crisis, the information in this section is particularly likely to change.Continuous evaluation through homeworks and projects.
Oral exam for the theoretical part. In case of failure of the oral exem, the final mark will reflect this failure.
