The biggest concern of pumping out water from this deep is the gradual settling down of the landsurface.
从这么深的地方抽水，最大的问题是地表会逐渐下沉。

In particularly wet years, short stretches of an otherwise dry stream-bed may have flowing water because the water table rises to intersect the landsurface.
在气候特别湿润的年月里，平常干涸的河床下游可能会有水流动，因为地下水在那里位抬升到了地表以上。

If the water table intersect the landsurface, groundwater will flow out onto the surface at springs, whether to be collected there or to subsequently flow farther along a drainage.
