A third-order accurate numerical method for the 2D shallow water equations, inclusive of the convection-diffusion terms due to the streamlines curvature, is discussed. The hydrodynamics and the behavior of a passive contaminant are analyzed, using recent advances in river mechanics and novel findings in RKDG methods. The comparison with selected laboratory data shows that good results can be obtained using relatively coarse grids, supporting the use of high-order methods in engineering practice.

Abstract
A third-order accurate numerical method for the 2D shallow water equations, inclusive of the convection-diffusion terms due to the streamlines curvature, is discussed. The hydrodynamics and the behavior of a passive contaminant are analyzed, using recent advances in river mechanics and novel findings in RKDG methods. The comparison with selected laboratory data shows that good results can be obtained using relatively coarse grids, supporting the use of high-order methods in engineering practice.File in questo prodotto:
