Interception (water)

Because of evaporation, interception of liquid water generally leads to loss of that precipitation for the drainage basin, except for cases such as fog interception, but increase flood protection dramatically, Alila et al., (2009).

[3] Intercepted snowfall does not result in any notable amount of evaporation, and most of the snow falls off the tree by wind or melts.

Mitscherlich in 1971 calculated the water storage potential as interception values for different species and stand densities.

Trees like Norway maple and a small-leaved lime have an interception of approximately 38% of the gross precipitation in temperate climate.

Interception may increase erosion or reduce it depending on the throughfall effects.
