2D Hydraulic Modelling Of The Pianas Dike
Failure

Abstract
The aim of this hydraulic modelling is to evaluate the risks that the Pianas dike
failure might generate to a railway embankment that borders the reservoir.
The simulations of breaching are made on two different places, that are chosen
for their vulnerability. For each place, two different widths of the breach are
simulated.
The modelling is carried out in two steps :
- The simulations of breaching based on the Meyer-Peter-Miiller relation.
- The simulations of the water propagation, based on 2D shallow water
equations.
For the hydraulic modelling, we do not take into account sediment motion and we
suppose that the dike failure is independent of the downstream waterflow
propagation.
The calculations of breaching during flood event give a very
