20.500.12556/RUL-131002 Influence of raindrop size distribution on throughfall dynamics under pine and birch trees at the rainfall event level Part of precipitation is intercepted by forest canopies, while the rest reaches the ground as throughfall or stemflow. This process is influenced by various meteorological variables, of which we have mainly focused on drop diameter and velocity. Rainfall in the open and throughfall under birch and pine trees have both been measured since 2014 in Ljubljana, Slovenia. The results demonstrate that the total throughfall during 3.5 years was 73% and 53% of rainfall under birch and pine trees, respectively. During the 236 analysed events, the median volume diameter was 1.8 mm (±1.7 mm), and kinetic energy between 0.01 mJ/cm$^2$ and 23.3 mJ/cm$^2$ was recorded. We closely analysed the effect of rainfall microstructure on throughfall under pine and birch trees during three specific rainfall events. The increase in drop diameter and fall velocity during a rainfall event instantaneously increased throughfall under pine trees between 25% and 47%, whereas no such changes were observed under birch trees. This may be the consequence of different tree properties of the two species. Additionally, in the case of a saturated canopy, throughfall under pine trees exceeded rainfall in the open after an onset of larger and faster drops. hydrology rainfall rainfall interception throughfall raindrop size distribution drop velocity birch pine Slovenia hidrologija padavine prestrežne padavine prepuščene padavine porazdelitev velikosti kapljic hitrost kapljic breza bor Slovenija true false true Angleški jezik Slovenski jezik Članek v reviji 2021-09-21 09:20:49 2021-09-21 09:20:52 2022-09-10 04:09:19 0000-00-00 00:00:00 2017 0 0 15 str. iss. 12, art. 240 Vol. 8 Dec. 2017 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 556.1 2073-4433 10.3390/atmos8120240 8231265 RAZ_Zabret_Katarina_2017.pdf RAZ_Zabret_Katarina_2017.pdf 1 75AECAD1181640E7F729B50DD4445E67 d7e1e5d6bf9fcb5dfc7ba665c221c0e9bd71111807a79b4bbc3450b15036463d 92bd7593-1aac-11ec-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=148220 http://www.mdpi.com/2073-4433/8/12/240 1 2ff8eae5-1aac-11ec-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=148219 Fakulteta za gradbeništvo in geodezijo Fakulteta za matematiko in fiziko 0 0 0
