Geography and topography

Wetlands occur where the topographic and geologic conditions are right and there is a sufficient supply of water water to keep the area wet for a long enough period of time. The typology and geology will not only influence the position of a wetland but also the type of wetland.

Wetland topography is one of the attributes looked at when applying the Queensland wetland habitat classification scheme. The layer used is derived from topographical maps and vegetation mapping layers to identify different landforms. Three relatively simple landforms are proposed based on floodplain, non-floodplain (springs, soaks and karst), and non-floodplain (depressional).
