Classification of Water Resources Top End and Arid Zone (Climate Zones)

This polygon spatial dataset defines the Top End region and Arid Zone regions as defined by the Northern Territory Water Allocation Planning Framework. The regions are also referred to as NT Water Resource Climate Zones.

The delineation uses the boundary between surface water catchments draining northwards into the Timor Sea or the Gulf of Carpentaria (Top End) and those flowing inland (Arid Zone). It is underpinned by a Top End index that draws from publicly available water balance indicators. These regions give an indication of the likelihood that a water resource will have the characteristics of a Top End or Arid Zone resource for guidance in water planning, management and regulation.

The zones are displayed in NR Maps - https://nrmaps.nt.gov.au/nrmaps.html --- See folder: Water > Water Resources. Layer name: Climate Zones.
