一、地下水库的概念和工作原理自然界存在着水的循环。水从海岸表面蒸发移到陆地上形成降水,而后再流到海洋里去。海洋每年从河流和地下径流而增加的水量抵消了由于蒸发而减少的水量。地下径流是怎样发生的?降落到地面的大气水份,一部分渗入地下成为土壤水,但大部分成为重力水下渗到土壤裂隙和空隙中。土壤空隙是由于形状、大小各不相同的相互交织着的节状孔道所组成的。当土壤空隙被饱合,便形成具有一定坡降 First, the concept and working principle of the underground reservoir There is a water cycle in nature. Water evaporates from the surface of the sea to land on the surface to form precipitation before it flows to the sea. The amount of water that the oceans increase from rivers and subsurface flow each year offsets the amount of water that is reduced by evaporation. How does underground runoff occur? Part of the atmospheric moisture that falls to the ground permeates into the ground and becomes soil water, but most of it becomes gravitational and underwater seepage into soil crevices and gaps. Soil space is due to the shape and size of each other intertwined nodular channel formed. When the soil gap is saturated, it will form a certain gradient
