Scientific issue
Development of a calculation code allowing hydro-sedimentary calculations to be carried out over long domains (several hundred kilometres) and over the long term (several tens of years). The Mage calculation code solves the one-dimensional Barré-de-Saint-Venant equations; the AdisTS calculation code solves the advection-dispersion equation of a sediment/pollutant concentration with potential exchanges with the bottom via a source term.
Questions scientifiques
- Development of a parallelized calculation code allowing efficient calculation times
- Reflections on the consideration of exchanges at the riverbed/water column interface at the section scale (minor and middle river beds)
- Understanding of the dynamics of fine sediments over a long reach
- Longitidinal grain sorting linked to suspension
Methods and results
- Development of a numerical model of the River Rhône including dam regulation laws (Dugué et al., 2015)
- Development and validation of source terms (erosion, deposition) in the AdisTS code(Guertault et al., 2016), application on the modelling of the Génissiat dam reservoir on the River Rhône during flushing events
