AN ASSESSMENT OF ROCKFALL FREQUENCY FOR THE COASTAL CLIFF-LINES OF PITTWATER LOCAL GOVERNMENT AREA, SYDNEY

摘要

The data presented in Table 1 and Section 4 above, represents the available data on coastal cliff-line rockfalls in Pittwater LGA over the last 15 years. For the reasons outlined above, the frequency data presented should be regarded as a lower bound indicator. Ongoing documentation and engineering geological assessment of rockfall events is encouraged by the author, so that frequency data can be refined, through a closer understanding of the relationship between rockfalls and coastal geological models.
