Reviewing Landslide Hazard Assessment Systems within South East Queensland

摘要

The study involved reviewing and evaluation of four Landslide Hazard Assessment Systems beingrnoperated by local government authorities within South East Queensland. The four authorities arernthe City of Gold Coast, Scenic Rim Regional Council, Logan City Council and Redland City Council.rnThese four authorities are all located generally to the south of Brisbane have different landslidernhazard assessment systems in place. The overall area covered by these local government areas isrnover 7000 square kilometres and has a population of over 975,000 people. The areas have variablerngeology and geomorphology that include significant areas of sloping terrain. The project involved arnreview and evaluation of the landslide hazard zoning systems, assessment of the existing planningrnschemes relating to the development on sites potentially susceptible to slope instability andrnevaluation of each of the systems with respect to the recommended assessment methods outlined inrnthe Australian Geomechanics Society Landslide Risk Management Guidelines 2007.
