Abstract

This Thesis studies the safety assessment method for macro-stability of dikes with high foreshores. Currently, this method is a semi-probabilistic method, which does not take the presence of a foreshore into account. The research concludes that the presence of a foreshore has a significant influence on the failure probability with respect to macro-stability of dikes. The semi-probabilistic assessment method therefore overestimates the failure probability of dikes, which can lead to unnecessary expenses for dike reinforcements. Possible improvements for the safety assessment method are discussed.
