Karst Hazards in the Wanneroo Area, Perth, Western Australia – 2003
Karst topography is a landscape shaped by the dissolution of a layer or layers of soluble bedrock, usually carbonate rock such as limestone or dolomite. Many karst regions display distinctive surface features, with dolines or sinkholes being the most common. Within the Perth region, a karst belt lies five kilometres inland from the coast and stretches approximately 24 kilometres in a north-west to south-east direction. This area is made up of one main geological unit, the Tamala Limestone, which is surrounded by residual sands formed from the erosion of the limestone. This report details a karst hazard map for the Wanneroo Local Government Area and is intended to provide regional awareness of the karst hazard.
