Throughfall
From Wikipedia, the free encyclopedia
In Hydrology, throughfall is the process which describes how wet leaves shed excess water onto the ground surface. These drops have an erosive power because they are larger than rain drops,however, they also travel a shorter distance so their erosive power is reduced.
Rates of throughfall are higher in areas of forest where the leaves are broad-leaved, this is because the flat leaves allow water to collect. Rates of throughfall are lower in coniferous forests as conifers can only hold individual droplets of water on their needles.
