Abstract
The accurate representation of morphodynamic processes and the ability to prop-
agate changes in the riverbed over a wide range of space and time scales make the
design and implementation of appropriate numerical schemes challenging. In partic-
ular, 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
