Kako vegetacija spreminja lastnosti dežnih kapljic

The process of rainfall interception is an important part of the hydrological cycle in many regions. The rainfall which is intercepted by vegetation evaporates into the atmosphere, while throughfall and stemflow contribute to runoff generation, control soil moisture and affect soil erosion. These topics are closely connected to the aims of the ongoing bilateral research project between University of Ljubljana, Slovenian Forestry Institute and TU Wien. The project focuses on the understanding of the effect of meteorological and vegetation characteristics on changes in raindrop microstructure. The rain drop diameter and velocity of raindrops under vegetation, which reach the ground by dripping from leaves and branches as throughfall, are different than diameter and velocity of rain drops above the canopy.
