20.500.12556/RUL-133286 Evaluating the influence of rain event characteristics on rainfall interception by urban trees using multiple correspondence analysis Urban trees play an important role in the built environment, reducing the rainfall reaching the ground by rainfall interception. The amount of intercepted rainfall depends on the meteorological and vegetation characteristics. By applying the multiple correspondence analysis (MCA), we analysed the influence of rainfall amount, intensity and duration, the number of raindrops, the mean volume diameter (MVD), wind speed and direction on rainfall interception. The analysis was based on data from 176 events collected over more than three years of observations. Measurements were taken under birch (Betula pendula Roth.) and pine (Pinus nigra Arnold) trees located in an urban park in the city of Ljubljana, Slovenia. The results indicate that rainfall interception is influenced the most by rainfall amount and the number of raindrops. In general, the ratio of rainfall interception to gross rainfall decreases with longer and more intense rainfall events. The influence of the raindrop number depends also on their size (MVD), which is evident especially for the pine tree. For example, pine tree interception increases with smaller raindrops regardless of their number. In addition, MCA gives a new insight into the influence of wind characteristics, which was not visible using previous methods of data analysis (regression analysis, correlation matrices, regression trees, boosted regression trees). According to the nearby buildings, a wind corridor is sometimes created, decreasing rainfall interception by both tree species. rainfall interception throughfall multiple correspondence analysis (MCA) rainfall event characteristics urban trees hydrology prestrezanje padavin prepuščene padavine multipla korespondenčna analiza (MCA) lastnosti padavinskega dogodka urbana drevesa. hidrologija true false false Angleški jezik Slovenski jezik Članek v reviji 2021-11-19 12:39:17 2021-11-19 12:39:20 2025-08-08 13:20:33 0000-00-00 00:00:00 2019 0 0 Str. 1-13 št. 12, 2659 Letn. 11 2019 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 556.5(497.4) 2073-4441 10.3390/w11122659 8995681 RAZ_Zabret_Katarina_2019.pdf RAZ_Zabret_Katarina_2019.pdf 1 1604C3D314AAB0A823276384702C19C5 bb1455003a18d4bb7638f00fbc991410af2f026cf06c6d13c35162d9a1216b38 894a4523-492d-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=151209 https://www.mdpi.com/2073-4441/11/12/2659 0 7cc08859-492d-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=151208 Fakulteta za gradbeništvo in geodezijo 0 0 0
