Hydrologic sciences - Interception, Precipitation, Runoff: When precipitation reaches the surface in vegetated areas, a certain percentage of it is retained on or intercepted by the vegetation. Rainfall that is not intercepted is referred to as throughfall.

Interception refers to precipitation that does not reach the soil, but is instead intercepted by the leaves, branches of plants and the forest floor. It occurs in the canopy (i.e. canopy interception), and in the forest floor or litter layer (i.e. forest floor interception ).
hydrologic cycle. In hydrosphere: Distribution of precipitation. This process is termed interception and may result in little water reaching the ground because the water may be directly evaporated from plant surfaces back into the atmosphere. If precipitation reaches the ground in the form of snow, it may remain there for some time.

Most transpiration occurs several hours or days after a rain event, whereas interception is immediate. In agreement with previous research, our simulations suggest that the vegetation’s ability to transpire by retaining and accessing soil mois-ture at greater depth is critical for sustained evaporation during the dry season.
In this definition, interception is merely the amount of water retained by the leaves of a tree. This is not a very workable definition for hydrologists since it leaves evaporation from land surface not catered for.
We conclude that interception mainly works as an intensifier of the local hydrological cycle during wet spells and wet seasons. On the other hand, transpiration remains active during dry spells and dry seasons and is transported over much larger distances downwind, where it can act as a significant source of moisture.
