DISCUSSION OF MEGACLAST TRANSPORT AND EROSION OF ROCKY SHORELINES:A COMMENT ON WILLIAMS (2010)

摘要

A recent paper by Williams (2010) described very large boulders (megaclasts) from the Aran Islands,Galway Bay, and argued that wave overtopping of high cliffs caused clast detachment and landward transport by wave bores. Here I highlight limitations of Williams’s arguments, and show that clast detachment and transport involves complex processes and conditions not considered in his paper.
