A grand prix basin
The Grand Canal Basin is a basin in northeastern Australia and has a large amount of groundwater. The central part of the central jersey is the inland watershed, with the largest watersheds of various rivers intruding into the Lake of Air. Not to mention the river in the inner watershed, even large rivers such as the Darling River are becoming intermittent rivers that are rarely seen. Geologically, this area is not subjected to severe crustal movements, and strata from the Paleozoic age are deposited and show the structure of branches. The porous layer exposed to the surface in the eastern highland is located at a depth of several hundred meters below the surface in the central part of the central lowland, but part of the precipitation in the eastern highland is osmotic to that layer and deeply exists as the pressurized groundwater in the central lowland is. Thus, the excavation wells reaching the aquifer pass through the impervious layer and see the groundwater discharge.
