As part of the research programme on the strength of clay with grass cover on the upper slope of a dike, large scale physical model testing has been performed. These physical model tests where the first step within the programme. In the second step the CFD model OpenFoam has been used to broaden the range of application of the model results by varying different parameters that may influence the erosion rate. With all results, it was possible to derive formulas for failure probability calculations in the final step.
This paper will first focus on the physical model that was built in the Delta Flume of Deltares at model scale 1:1.
