DOI: 10.1002/fld.4500
Abstract: Erosion and sediments transport processes have a great impact on industrial structures and on water quality. Despite its limitations, the Saint-Venant–Exner system is still (and for sure for some years) widely used in industrial codes… read more here.

DOI: 10.1109/tgrs.2016.2621124
Abstract: We present a discontinuous Galerkin pseudospectral time-domain (DG-PSTD) algorithm to solve elastic-/acoustic-wave propagation problems. The developed DG-PSTD algorithm combines the merits of flexibility from a finite-element method and spectral accuracy and efficiency from a high-order… read more here.
