This information has been developed from one or more of these publications:

  • Sites of Geological and Geomorphological Significance in the Westernport Bay Catchment (1984) by Neville Rosengren.
  • Sites of Geological and Geomorphological Significance in the Western Region of Melbourne (1986) by Neville Rosengren
  • Sites of Geological and Geomorphological Significance on the Coast of Port Phillip Bay (1988) by Neville Rosengren.
  • Sites of Environmental Significance in the Flood Plain of the Upper Yarra Valley Region (1983) by Neville Rosengren, Douglas Frood and Kim Lowe (as part of a study of Sites of Environmental Significance by the University of Melbourne for the then Upper Yarra Valley and Dandenong Ranges Authority).
Geological heritage sites, including sites of geomorphological interest and volcanic heritage sites, are under regular revision by the Geological Society of Australia, especially in the assessment of significance and values. Reference should be made to the most recent reports. See the Earth Science Heritage section of the Geological Society of Australia website (external link) for details of geological heritage reports, and a bibliography.

Tankerton Creek. Arrows show undercut banks and dotted line is former shoreline. Truncated meander (A) is a result of shoreline erosion, Site 209

Access:

Coast Road.

Ownership:

Crown land.

Geomorphology:

The lower reaches of Tankerton Creek are tidal and the channel displays tight meander bends. Erosion and undercutting take place on the outside of the meander bends. Shoreline erosion following die-back of mangroves has shortened the length of the creek leaving the former outlet as a truncated meander.

Significance:

Regional. The site displays several physiographic changes that can occur as a result of mangrove die-back.

Management:

Class 1. As the erosion does not threaten any property, it is not necessary to carry any bank stabilization schemes or to attempt to reduce erosion rates of the coast or the stream channel.
