Which term corresponds to water that falls through vegetation?

• A. Channel
• B. Groundwater
• C. Throughfall
• D. Leakage

Answer: (C)

Throughfall is the water that reaches the ground after rain passes through the vegetation. When rain falls on a canopy, leaves and branches intercept some of it, storing or evaporating a portion. The remaining water that makes it through gaps in the canopy drips or falls to the forest floor as throughfall. This distinguishes it from water that flows along stems (stemflow) or water confined to channels or underground (surface channels or groundwater). In essence, throughfall is the rainfall that actually reaches the soil after interacting with the vegetation.
