Discussion on 'Dam break in rectangular channels with different upstream-downstream widths'

Résumé

Discussion on the publication 'Dam break in rectangular channels with different upstream-downstream widths' (Valiani and Caleffi, 2019). The authors consider an augmented shallow water system for modelling the dam-break problem in a channel with discontinuous width and present its analytical solutions depending on the upstream-downstream water depth and channel's width ratios. In this discussion we contest the conservation of the hydraulic head through the width's discontinuity, which is stated by the authors, and we exemplify it by performing 2D Shallow water simulations reproducing some test cases presented in the paper.
