hydrologic cycle 水文循環

Figures 1.1 and 1.2 illustrate that some precipitation evaporates before reaching t
he earth and remains in the atmosphere as water vapor .
Water also evaporates after reaching the earth .
Plants take up infiltrated water and groundwater and return a portion of it to the atmosphere through their leaves , a process known as transpiration .
Some infiltrated water may emerge to surface-water bodies as interflow , while other portions may become groundwater flow .
Groundwater may ultimately be discharged into streams or may emerge as springs .
After an initial filling of interception and depression storages , and providing that the rate of precipitation exceeds that of infiltration , overland flow (surface runoff) begins .
The magnitude and duration of a precipitation event determaine the relative importance of each component of the hydrologic cycle during that event .
During storm events , evaporation and transpiration may be minor considerations , for example , but during rain-free periods , evapotranspiration becomes a dominant feature of the hydrologic cycle.
