SUMMARY:Adaptive multiscale discontinuous Galerkin methods for multiphase 
 morphodynamics - Michoski\, C (University of Texas at Austin)

DESCRIPTION:We present a strongly coupled\, eigendecomposition problem for
  an extension of the SaintVenant shallow water equations in two dimensions
  strongly coupled to a completely generalized Exner form of the sediment d
 ischarge equation. This formulation is used to implement an adaptive disco
 ntinuous Galerkin (DG) finite element method\, using a Roe Flux for the ad
 vective components and the unified form for the dissipative components. We
  discuss important mathematical and numerical nuances that arise due to th
 e emergence of nonconservative product formalisms in the presence of sharp
  gradients\, and present some large scale candidate application models wit
 h examples\n
