hydrologic

While evaporation from the oceans is the primary vehicle for driving the surface-to-atmosphere portion of the hydrologic cycle, transpiration is also significant..海洋的蒸发作用是水文循环中的主要方式，它使得水从地球表面进入大气层中，蒸腾作用也具有举足轻重的地位。

Only when a system possesses natural or artificial boundariesthat associate the water within it with the hydrologic cycle may theentire system properly be termed hydrogeologic..只有当某一地质系统拥有自然的或人工的界限，将该系统内的水与水文循环起来，这整个系统方能被恰当地称为与水文地质学相关。

Natural disasters are catastrophic events with atmospheric, geologic, and hydrologic origins. Disasters include earthquakes, volcanic eruptions, landslides, tsunamis, floods, and drought..自然灾害是指大气、地质或水文等因素造成的灾变，包括地震、火山爆发、泥石流、海啸、洪水和干旱等。
