Landslides: An alternative method of landslip zonation in the Tamar Valley, Northern Tasmania

Decisions made concerning the management and landuse of sloping areas subject to landsliding are dependent on a set of criteria which assessments can be based around. This paper offers a revised method of grading landslip risk by the integration of additional data to that used by Mineral Resources Tasmania. The method is assisted by the evaluation and development of geological, morphological and hydrological models using Geographic Information Systems (GIS). Two active landslides, Gaunts and Native landslides, were used to test the validity of the GIS method.
