Goal(s)
Students will become acquainted with the pluridisciplinary aspects of this topic.
Student will be asked to master: the concept and the quantitave determination of sediment mouvement inception, computation of sediment transport rates, the concept of sedimentary equilibrium (river bed slope, grain size distributions), engineering tools of the field
Content(s)
1. Fundamental concepts: the various modes of sediment transport, the materials, introduction to river morphology.
2. Elementary analysis of the bed-load mechanism: threshold conditions of sediment movement, sensitivity of Meyer-Peter and Müller formula.
3. 1D analysis of sediment transport: predictive formulaes and their range of applicability.
4. Deeper in the mechanisms of the sediment transport: transport in suspension, grain roughness, shape roughness, dune and bed forms, secondary currents, transported grain size distribution and bottom grain size distribution, grain size sorting by the flow, hiding effects & armoring.
5. Tools engineering studies: the morphological diagnosis and the models.
