For example, a pond in hilly country that maintains a steady water level all through a dry summer in spite of having no streams flowing into it must obviously be seepage dominated.
例如，在丘陵地区的一个池塘，尽管没有小溪流入但在整个干燥的夏季保持稳定的水位，显然一定是以渗流为主。
It ranges from sea level in the Polar Regions to 4,500 meters in the dry subtropics and 3,500-4,500 meters in the moist tropics.
它的范围包括海平面的极地地区、4500米高的干燥的亚热带地区以及3500-4500米高的潮湿的热带地区。
Because it is located in a very hot and dry region, the Dead Sea loses much water through evaporation, causing its level to fluctuate during the year.
因为它处于一个非常炎热和干燥的地区，死海由于蒸发损失掉大量的水，导致其水平面一年到头不断波动。
