Geology and natural water systems


On 21 September 2015, responsibility for water policy and resources was transferred to the Department of Agriculture and Water Resources - Administrative Arrangement Order made on 21 September 2015.

This website will be updated to reflect these changes.

The Earth's natural features have been formed by chemical and physical processes over millions of years, and are constantly changing. Natural water systems are determined by the geological characteristics of an area and the influence of chemical and physical processes associated with the water cycle.

The key concept of geology and natural water systems explores the many places where water can be found in the natural landscape and provides information on the geological formation of these systems. Examples include:

  • Streams, creeks and rivers
  • Oceans and seas
  • Estuaries, inlets and bays
  • Lakes, dams, ponds and wetlands
  • Glaciers
  • Groundwater and aquifers
  • Weathering and erosion of natural systems though both chemical and physical processes associated with water
  • Geological change through freezing and melting of water inside rocks
