- Abstract
- The Corangamite region covers an area of approximately 13,340 km2 and is located in south western Victoria, Australia. The population of approximately 400,000 persons is growing at 5.2% per year, and is served by nine municipalities within the region. The region's diverse range of landscapes and climatic conditions, result in a variety of geological hazards including landslides, soil erosion of all forms, coastal erosion, dryland salinity, potential acid sulphate soils, reactive soils and ground subsidence. These geohazards are increasingly recognised as a constraint on future urban development and a threat to the economic, social and environmental health of the region. Evaluation of the impacts of geological hazards by State government authorities, research institutions and consultants has been inconsistent, both in hazard identification and risk assessment methods. As a result, municipal planning authorities have lacked a consistent framework with which to assess the potential impacts from these hazards and those associated with new developments which may interact with the hazards. The use of risk assessment techniques for the management of landslides in Australia advanced significantly after the publication of the Australian Geomechanics Society's landslide risk management concepts and guidelines in 2000. These guidelines in turn were based on the Australian/New Zealand Standard on Risk Management. Similar risk management techniques have now been developed by the authors for the assessment of soil erosion and salinity for particular use by municipalities within the Corangamite region. A brief review of the nature and extent of landslides, salinity and erosion in the Corangamite region is detailed. The adopted methods of the risk management for each geohazard are described including a comparison of their applicability and an assessment of limitations with each method.; E1
