Where is Ti Tree?
The Ti Tree Basin is located approximately 150 km north of Alice Springs. It is located within Australia’s dry tropics, with an annual rainfall of approximately 300 mm, and covers an area of 5500 km square. Groundwater in the Ti Tree Basin is used for irrigation of horticultural crops, and town and community water supplies.
Research is being undertaken in various locations, including the Woodford River, Stirling Swamp and Allungra Creek.
Why is this location important?
Recharge to the aquifers is believed to occur in the southern and central parts of the basin, as slow percolation through the soil (diffuse recharge), and also as flood recharge associated with the ephemeral rivers. These process are not well understood, and it is expected that research in this region will not only clarify local recharge processes, but also shed light on similar systems elsewhere in the world.
