Abstract :

[en] Based on an operational 2D shallow-water model, the Authors computed subcritical dividing flow at a three-branch crossroad, considering obstacles located at different positions. The numerical predictions were compared to observations from Mignot et al. (2013). Two issues are addressed here, related respectively to the efficiency and relevance of the turbulence model, and to the representation of the obstacles in operational flood models.
