Groundwater commonly collects in stream drainages but may remain entirely beneath the surface of dry stream-beds in arid regions.

地下水通常聚集在河流流域，但在干旱地区，地下水也可能完全保留在干涸河床的表面之下。

Wetlands have a big effect on groundwater, the amount of water below the surface of the land.

湿地对地下水，即地表以下的水量影响很大。

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

如果地下水位与地表相交，地下水将在泉水处流出地表，聚集于此或是随后沿着排水系统进一步流动。

The water footprint includes both the water withdrawn from surface and groundwater and the use of soil water (in agricultural production).
