| Abstract |
The paper presents a qualitiative analysis on the results from the experiment. This includes a theoretical analysis of the shear stresses exerted on the landside slope of the embankment during overflow and wave overtopping. The paper furthermore comments on the current state of the art theories describing the resisual strength of grass. Based on the results from the experiment it was noted that current theories describing the residual strength of grass covers subject to overflow are very conservative. The analysis of the theorie and data furthermore show that the failure processes during wave overtopping differ significantly from the failure processes during overflow. In the case of wave overtopping it is insufficient to solely account for the shear stresses i:n determining failure initiation. After the grass cover failed both simulators were used to analyse the breach formation processes. It was noted that the breach formed due to headcut formation and that the headcut formation was maintained when the flow reached the sandy core. A link with the field of dredging engineering is ~ade in the paper to explain the processes. |
