Numerical evaluation of stability methods for rubble mound breakwater toes

Since 1977 dedicated studies are made to the stability of rubble mound break-water toes under wave attack. A large number of stability methods is available, but prediction accuracy is low and validity ranges are too small for use in prac-tice. In this research the decoupled model approach is used to evaluate predic-tion capacity of existing toe...

Toe rock stability for rubble mound breakwaters

Present design tools, as found in the Rock Manual or Coastal Engineering Manual, for the determination of toe rock size for rubble mound breakwaters are based on test data with a large spread: data is relatively dispersed around the centre and descriptive equations have limited applicability ranges. New research has been undertaken to contribute...

Flow velocity at rubble mound breakwaters

Measurements of flow velocities due to wave action on top of shallow toe structures in front of a rubble mound breakwater. Laboratory tests in the Fluid Mechanics lab, TU Delft.

Toe structure stability of rubble mound breakwaters

In this report an analysis of data from a series of tests is presented on the stability of the toe structure of rubble mound breakwaters. The existing knowledge on toe stability and the influence of all governing parameters in the existing knowledge is reviewed. The tests which were performed for the present research are treated extensively. The...
