ABSTRACT
Internal Erosion initiated by water movement along channels called tunnel erosion, often
crack or defect the dam?s structure. It is one of the main causes of water structure?s (dams,
dikes, etc.) collapse. This phenomenon can be divided into 3 phases, tunnelling, collapse, and
the opening of the channel inside the dam [1]:
- ?Tunnelling? transport large quantities of particles due to the hydraulic gradient. It?s happen
fast in a preferential path especially in some point of dam structure?s weaknesses.
- The ...

This paper presents a set of numerical simulations of different 2D boundary-value problems in order to validate a “smoothed-particle hydrodynamics”-“arbitrary Lagrangian-Eulerian” (SPH-ALE) code. This code is intended to be used to study, among other things, the problem of piping erosion in dams and dikes. The case of viscous fluid flows around a fixed cylinder was first examined. Different Reynolds numbers and different shapes for the cylinder were considered. The drag coefficient, lift coefficient, pressure coefficient, ...
