A discontinuous Galerkin finite element model for river bed evolution under shallow flows
The accurate representation of morphodynamic processes and the ability to propagate
changes in the riverbed over a wide range of space and time scales make the design and
implementation of appropriate numerical schemes challenging. In particular, requirements of
accuracy and stability for medium and long term simulations are difficult to meet. In this work,
the derivation, design, and implementation of a discontinuous Galerkin finite element
method (DGFEM) for sediment transport and bed evolution equations are presented …
