NCRIS Groundwater Infrastructure



Where is Namoi?

The Namoi River is a major tributary to the Darling River, and flows through inland NSW. The Namoi catchment incorporates Tamworth, Narrabri and Walgett. The Namoi catchment is an important cotton-growing region, and part of the Murray–Darling Basin.

Why is this location important?

The Namoi is the most over-committed groundwater basin in Australia. Research in this area could significantly advance our understanding of alluvial groundwater resources.
