Rock 'n' Roll in Mound Structures

Per Bruun


This note was inspired by recent years' efforts on improvements of the design and construction of mound structures for breakwaters and coastal protection. Although improved procedures have been implemented in many projects, misleading approaches still occur. Research in unit structural stability, still in its infancy, suffers from the lack of proper hydroelastic model laws that enable correct representation of the prototype in the model. Block geometries are still discussed but more sophisticated compact blocks are becoming popular as experience about their function becomes more widely appreciated and available.
