A detailed analysis of failure modes for seadikes has been performed and was used to derive a complete set of limit state equations for the description of failure scenarios of seadikes. These models and scenarios were then used to calculate the respective failure probabilities and the overall failure probability by a fault tree approach. A simple example of a non-existing seadike was used to illustrate the procedure. Details of parameters, model uncertainties and their influences on the results as well as further information required for the aforementioned procedure are also discussed.

Prediction of overtopping

It is proven that wave run up on rough slopes is underestimated in small scale model tests due to scale / model effects. Given this fact, the same effects are suspected to be present for wave overtopping. A thorough comparison between prototype measurements of wave overtopping at three different coastal structures and scale model tests of these structures has been performed. The present paper gives the results from this comparison and presents a procedure to determine whether scale effects can be present in a certain situation. The procedure allows to calculate the magnitude of the scale and wind effect that can be expected. Since a lot of designs are based on physical model tests, this procedure has a broad range of applicability and its importance should be stressed.

Extreme storm surges can cause failures of flood defences resulting in severe flooding of the hinterland and catastrophic damages. In order to quantify the risk of flooding an integrated risk analysis is being performed wherein one task is the determination of failure probabilities of flood defences. In this paper the failure probability calculations of flood defence structures and systems under the loading of extreme storm surges are reported. Moreover, the analysis of the breach and breach development is briefly introduced. Preliminary results of the failure probabilities and the breach modelling are presented using the example of the estuarine urban area of Hamburg, Germany. These results are put in context of an integrated risk analysis approach for extreme storm surges which is applied within an ongoing German joint research project.
