Organisation and examination
Teaching in the second semester
Units courses prerequisite and corequisite
Prerequisite or corequisite units are presented within each program
Learning unit contents
The hydraulics and mechanics of open channel flow. Erosion and sediment transport. Catchment denudation and sediments yield : solute transport dynamics, suspended sediment transport, bedload transport (Equations of Meyer-Peter, Bagnold...). Runoff erosion and gullies formation : application of the Es model. Evolution of the river patterns in response of Quaternary climatic changes. Bed stability and sedimentary structure (armouring effect, pebbles clusters, step pool system). River channel changes and adjustments : the effects of man (land-use changes, urbanization, extractive industries, the downstream effects of reservoir impoundment). Cartography of the flooded areas (hydrogeomorphologic method).
Learning outcomes of the learning unit
This course considers the various methods and concepts of river dynamics, within the framework of applications to river management
Prerequisite knowledge and skills
Course of geomorphology
Planned learning activities and teaching methods
Practical works consist to field works (discharge measurement; techniques of marking and sampling of sediments), treatments related to hydrological and sedimentological data. Maps and aerial photographs analysis.
Mode of delivery (face-to-face ; distance-learning)
- the hydraulics and mechanics of open channel flow;
- erosion and sediment transport (critical velocity, shear stress evaluation, stream power);
- catchment denudation and sediments yield; solute transport dynamics, suspended sediment transport, bedload transport. Runoff erosion and gullies formation.
