This research follows a fully probabilistic approach in order to estimate the optimal design for a river dike cross-section, taking into account the investment costs. From the theory studied, the failure mechanisms that contribute most to the failure of river dikes are identified. These are overflowing, wave overtopping, piping and inner slope stability. The most important design variables of the dike cross-section dimensions are set and following probabilistic design methods, the probability of failure of many different dike cross-sections is estimated based on the abovementioned failure mechanisms. The aim of the study is to develop a generic method that automatically estimates the failure probabilities of many river dike cross-sections and gives the one with the least cost, taking into account the boundary conditions and the requirements that are set by the user.
