Description: This dataset subdivides the spatial extent of the Kati Thanda - Lake Eyre Basin (KT-LEB) project region based on modified drainage division. The major ion compositions and groundwater types for hydrochemical samples for groundwater bores in the KT-LEB region are discussed in detail in Evans et al. (2024).The LEB hydrochemistry zones dataset is derived from the modified boundaries of the Bureau of Meteorology (2022) River Regions, Australian Surface Water Management areas (ASWMA 2005), based on 1997 Drainage basin dataset, and Queensland Drainage basin sub areas (Department of Resources,2021). Details regarding the sources and data attribution for KT - LEB Project boundaries dataset (Geoscience Australia, 2024) are outlined in further detail in the metadata relevant to that dataset.
