Publicatie type | rapport Deltares
This report deals with an evaluation of experimental tests at two locations Nijmegen and Millingen aan de Rijn. Models are here further developed to predict the consequences of wave overtopping on the strength of landward slopes. Also relations are established for estimating the effects of wave run-up on outer slopes. Measured flow velocities and flow depths on a landward slope due to overtopping waves are discussed in relation to the steady state theory of overflow. The flow velocities accelerate from the crest to the toe of the dike and are calculated adequately provided the friction factor is relatively small (i.e. f = 0.01). Although the computed flow depths are too small they are not needed as the cumulative overload method depends on flow velocities and critical flow velocities.
