In this msc thesis work, a 3-D eddy resolving modelling technique is presented that could help in formulation of a new stability formula to tackle erosion-related problems. It is the aim of this thesis to build a hydrodynamic numerical tool, able to predict governing mechanisms in stone stability. Special attention is paid on the way of representing a rough boundary and predicting wall and free turbulence. A Wall-Modelled Large Eddy Simulation (WMLES) is build using the open-source CFD toolbox OpenFOAM v.1812. Firstly, simple open channel flow case simulations are set-up, to evaluate the performance of rough wall functions in the LES environment. Secondly, a backwards facing step kind of flow from the experimental study of Jongeling et. al (2003) is simulated and the performance of the numerical model is evaluated based on the experimental results. The current dataset includes the input and output files of the numerical simulations of the aforementioned cases. The experimental dataset of Jongeline et al. (2003) used in this thesis is also included.
