aquifer

A groundwater reservoir from which water can be extracted is called an aquifer.

可以从中抽取水的地下蓄水层被称为含水层。

Extraction of water depends on two properties of the aquifer: porosity and permeability.

水的开采取决于含水层的两个性质：孔隙度和渗透性。

Water does not remain immobile in an aquifer but can seep out at springs or leak into other aquifers.

水在含水层中并不是静止不动的，而是会从泉水中渗出，或渗入其他含水层。

This aquifer was named the Ogallala aquifer after the Ogallala Sioux Indians, who once inhabited the region.

这个含水层被命名为奥加拉拉含水层，以曾经居住在这个地区的奥加拉拉-苏族印第安人的名字命名。

The situation is most critical in Texas, where the climate is driest, the greatest amount of water is being pumped, and the aquifer contains the least water.

这种情况在德州最为严重，那里气候最干燥，抽水量最大，含水层含水最少。
