Discussion of 'Discontinuous Galerkin Finite-Element Method for Simulation of Flood in Crossroads' by Rabih Ghostine, Emmanuel Mignot, Maher Abdallah, Fabrice Lawniczak, Jose Vazquez, Robert Mose, and Caroline Gregoire

摘要

The authors' work addresses the modeling of severe flood scenarios in urban street crossings by combining the analysis of numerical simulations and experimental results. In particular, the depth-integrated shallow water equations were solved numerically by a Runge-Kutta discontinuous Galerkin (RKDG) method, and solutions were compared with those obtained by a finite-volume (FV) method described in Wang and Liu (2000) and by experimental tests performed in a physical model introduced by Mignot et al. (2008).
