Interception is an important process of the hydrological cycle, although it has been often neglected in hydrological considerations (Gerrits et al., 2010). Generally, interception loss is understood as a part of precipitation detained on vegetation canopy or leaf litter. Where vegetation is present, precipitation consists of gross rainfall (observed above the canopy or in a nearby open field), canopy through-fall and stem-flow. In stratified forest communities, where water drips from the canopy and is still intercepted by lower plants, secondary interception occurs. David and Gash (1989) reports the interception loss from forests in the range from 8 to 60% of the gross rainfall (from 25 to 75% of the overall evapotranspiration).
