COURLIS modelling sediment transport in rivers and reservoirs where the flows can be considered as 1D. Evolution of riverbeds due to bedload transport is classically modelled by coupling the Shallow-Water equations for hydrodynamic processes (solved in the MASCARET solver) and the Exner equation for bedload mechanisms. COURLIS manages cohesive and non-cohesive sediment transport by suspension.
Example of applications
