Thus, there is a real need to explore in depth and understand the mechanisms at work in such complex erosional processes for preventing similar risks. The aim of this study is to provide a micromechanical insight into the mechanisms taking place during the erosion of a cohesive granular material driven by a fluid flow, the objectives are summarized as follows: Perform numerical erosion tests. Parallelization of the code (Gpu). Extensive parametric analysis => rely micro parameters (eg. Cohesion) to macro parameters (eg. Soil erodibility, mechanical strengths).
