Hydrology-Hydraulics Research Unit, Lyon, France 1 Sediment transport models used by Cemagref during Impact project André PAQUIER

Hydrology-Hydraulics Research Unit, Lyon, France 2 Aims of the models l Rubarbe:1-D model: bed-load by sediment discharge limited by transport capacity, evolution of main bed geometry during floods l Rubar20TS: 2-D model: suspended load by concentration, exchanges with bottom controlled by equilibrium concentration, evolution of flood plain deposits during floods

Hydrology-Hydraulics Research Unit, Lyon, France 3 1-D model RUBARBE

Hydrology-Hydraulics Research Unit, Lyon, France 4 Example of use of MPM

Hydrology-Hydraulics Research Unit, Lyon, France 5 2-D model RUBAR20TS

Hydrology-Hydraulics Research Unit, Lyon, France 6 Ptuj Lake

Hydrology-Hydraulics Research Unit, Lyon, France 7 Conclusions l 1-D model « validated » for usual floods in rivers and for some specific cases (flushing gate) l 2-D model « validated » for deposits in reservoirs l Complementary models, »both relatively simple but including (very) unsteady flow l Use possible for breaching, near field, far field?
