State of the art geotechnical engineering and project designare nowadays rigidly connected to the mindful adaption of the Eurocode. However, questions can be raised on the critical selection of the characteristic values for parameters such as the soil compressibility and permeability. The experiment conducted at Leendert de Boerspolder, where a dyke was controllably brought to failure, poses as an excellent circumstance for investigating this issue. After setting up an FEM model in PLAXIS 2D, as well as orchestrating multiple ULS schemes and comparing the available soil constitutive models, the effects of these characteristic values on the response of the system are explored. Displacement profiles are collated, but more importantly, the safety factors and possible failure mechanisms of every analysis are put under comparison. The outcome is the evaluation of the characteristic value pick on a quantitative and qualitative level. Thus, certain concepts regarding the application of the Eurocode in geotechnical engineering can be tackled or validated, allowing for a critical implementation of the norms.
