Abstract
Precipitation retained by tree canopies (~25%) is a key part of the forest water cycle, making our understanding of it vital for ecohydrological studies. Canopy interception varies seasonally with changes in canopy storage capacity. While remote sensing for rainfall partitioning is still developing, there is a strong demand for the calibration of canopy interception models based on ground measurements. In addition, most studies cover no longer than a few years, limiting long-term insights. Therefore, the main objective of this study is to upgrade a Merriam-type canopy interception model (derived partly from physical parameters) for European beech (Fagus sylvatica L.), which takes into account the dynamically changing reservoir capacity of the canopy (based on remotely sensed LAI data). The model was tested with annual precipitation totals for the period of 2017–2022. The results indicate that interception has a significant partitional effect on rainfall, which is notable in terms of its proportions, especially for small precipitation events (0–5 mm). The value of yearly interception was 20% (13% in dormancy and 24% in the growing season). The calibrated model can provide beech interception values in areas with similar climatic parameters to those of the study area.

Title:Fizično osnovan pristop k modeliranju prestrezanja padavin v bukovem gozdu z uporabo podatkov daljinskega zaznavanja
Abstract:
Padavine, ki jih zadržijo krošnje dreves (~25 %), so ključni del vodnega kroga v gozdu, zato je njihovo razumevanje bistveno za ekohidrološke študije. Prestrezanje padavin se spreminja sezonsko, odvisno od sprememb v skladiščni zmogljivosti krošenj. Medtem ko se daljinsko zaznavanje na področju prestrezanja padavin še razvija, obstajajo potrebe po kalibraciji modelov prestrezanja padavin z upoštevanjem meritev na terenu. Večina takšnih študij pa obsega največ nekaj let, kar omejuje dolgoročne vpoglede v proces. Zato je glavni cilj te analize nadgradnja Merriamovega modela prestrezanja padavin (delno izpeljanega iz fizikalnih parametrov) za evropsko bukev (Fagus sylvatica L.), ki upošteva dinamično spreminjajočo se zmogljivost krošenj (na podlagi podatkov LAI, pridobljenih z daljinskim zaznavanjem). Model je bil preizkušen z letnimi količinami padavin za obdobje 2017–2022. Rezultati kažejo, da ima prestrezanje pomemben učinek na prerazporeditev padavin, kar lahko opazimo predvsem s spreminjajočimi razmerji, zlasti pri manjših padavinskih dogodkih (0–5 mm). Vrednost letnega prestrezanja je bila 20 % (13 % v mirovanju in 24 % v rastni sezoni). Kalibriran model lahko uporabimo za ocene prestrezanja padavin bukve na območjih s podobnimi podnebnimi parametri kot na območju študije.
