Design formulas for bed protections in the port of Rotterdam were investigated. Using depthsoundings, the actual level of stability of a quay wall can be compared with the design formulas. The loads on a bottom protection differ, because of diversity in shipping and tidal motion. Therefore a better comparison can be made by resembling the results of the soundings with a probabilistic approach. The model is calibrated by the sounding results and by registrations of mooring and unmooring vessels. From these approaches insight in the influence of each input variable can be derived. By using a combination of probabilistic results and a fault-tree the probability of a scour hole near a quay wall can be calculated. Also the impact of a scour hole on the environment of a quay wall was investigated. With these results a risk based analysis is made to evaluate the different strategies and their consequences.
