Aeration in Rubble‐Mound Breakwater Models
Publication: Journal of Waterway, Port, Coastal, and Ocean Engineering
Volume 116, Issue 3
Abstract
An experimental program in which entrainment and movement of air bubbles within the voids of rubble‐mound breakwater models were investigated is described. Aeration was evaluated as a function of type of armor unit (stones, spheres, and cubes), breakwater slope, relative geometry of the structure, and type of core material. Aeration resulting from both external wave breaking and flow separation was observed. The relative extent of aeration was a function of the type of breaking wave observed. Aeration was more severe in structures constructed with highly permeable cores. Variations in void geometry and orientation had a significant influence on the motion of air bubbles into the structure.
