how old is the water in the great artesian basin
Great Artesian Basin Discharge water eventually exits through a number of springs and seeps, mostly in the southern part of the basin. The age of the groundwater determined by carbon-14 and chlorine-36 measurements combined with hydraulic modelling ranges from several thousand years for the recharge areas in the north to nearly 2Â million years in the south-western discharge zones.[7]
Topography These maps show not only the contours, but also any significant streams or other bodies of water, forest cover, built-up areas or individual buildings (depending on scale), and other features and points of interest.
Vein Veins are less muscular than arteries and are often closer to the skin. There are valves in most veins to prevent backflow.
