地下之水 · BURIED WATER

内陆荒原下的水盆

The Outback’s Hidden Basin — Australia · Great Artesian Basin

大自流盆地面积超过 170 万平方公里，占澳大利亚五分之一以上。在干旱内陆，地下压力与钻井让远离稳定河流的牧业定居成为可能。

地表地图写着距离、高温与稀少河流；隐藏地图写着含水层、泉眼与钻井线。正是第二层地理，让牧场和小镇得以坚持。

• >1.7M km² 盆地面积｜澳大利亚最大地下水盆地 (basin area, Australia’s largest groundwater basin)
• >1/5 澳大利亚国土｜官方口径 (of Australia, )
• ~65M GL 地下水量｜官方估值 (groundwater, )

The Great Artesian Basin covers more than 1.7 million km², over one-fifth of Australia. In dry interior country, underground pressure and bores made pastoral settlement possible far from reliable rivers.

The surface map shows distance, heat and sparse rivers. The hidden map shows aquifers, springs and bore lines — a second geography that let sheep stations and towns hold on.
