Notional Permeability

Different layer design of a rock slope and under layers has a large effect on the strengths on the rock slope itself. In the stability formula developed of VAN DER MEER [1988] this effect is represented by the term Notional Permeability with symbol P. A more open, or permeable, structure underneath the armour layer has the ability to dissipate...

Conceptual Design of Rubble Mound Breakwaters

This paper gives first an overall view of physical processes involved with rubble mound structures and a classification of these structures. After the description of governing parameters, the hydraulic response is treated. This is divided into: - Wave run-up and run-down, - Wave overtopping, - Wave transmission, - Wave reflection. The main part...
