“…Table 7 shows that the Gash method is the most stable between the two trees and among seasons (R 2 = 60 % ± 2 %, E RMS = 0.85 ± 0.2 mm), whereas the other methods show more variation. As reported by Véliz-Chávez et al (2014), the performance of the Rutter model is not as good as the performance of the Gash method. Similarly, we also observe an underestimation of the interception storage for higher rainfall events (P g > 10 mm) using the Rutter method (Fig.…”

“…Furthermore, throughfall is usually not equally distributed under the canopy, which makes upscaling results to the whole tree canopy level difficult. Another in situ measurement method is the collection of all throughfall under a tree via the construction of a v-catchment construction large enough to cover the canopy area (Véliz-Chávez et al, 2014;Xiao et al, 2000b). Throughfall and stemflow are usually collected in separate containers.…”

“…Several authors have attempted to quantify the contribution of urban trees to the total water balance. Some authors have looked at large areas of urban cover and have determined the water storage potential of the urban forest based on land-cover-derived maps (Gill et al, 2007;Haase, 2009;Verbeeck et al, 2013). To do so, they assign empirical storage capacity values to certain vegetation classes based on the literature.…”

“…This type of storage is relatively independent of meteorological characteristics. Vegetation characteristics determining the minimum storage capacity are the canopy architecture, the leaf and stem surface areas, the seasonal vegetation development and the tree's health (Asadian and Weiler, 2009;Véliz-Chávez et al, 2014;Xiao et al, 2000b). The second type of storage is the detention or maximum storage, this is the maximum amount of water that can temporally be stored on a vegetation unit.…”

Abstract. An in situ tree interception experiment was conducted to determine the hydrological impact of a solitary standing Norway maple and a small-leaved lime in an urban environment. During the 2-year experiment, rainfall data were collected and divided into interception, throughfall and stemflow. With approximately 38 % of the gross precipitation intercepted by both trees, the interception storage was higher than for similar studies carried out in Mediterranean regions. The specialized forest interception models from Gash (first published in 1978) and Rutter (first published in 1971), as well as an adapted solitary tree version of the Water and Energy Transfer between Soil, Plants and Atmosphere model (WetSpa), were tested for their accuracy in modeling the measured interception storage. The models generally overestimated interception storage for small interception events (< interception storage) and underestimated interception storage for bigger interception events (> interception storage). Gash's method slightly outperformed WetSpa and Rutter for all events throughout seasons and trees. However, WetSpa showed better performance for rainfall events > 10 mm. The similar performance of WetSpa and the Gash and Rutter models is noteworthy because the WetSpa interception model is part of a larger modeling framework that models the whole hydrological balance, whereas the Gash and Rutter methods are specialized stand-alone interception models. Thus, WetSpa is recommended to gain a more complete understanding of the impact of city trees on the full hydrological balance. This study emphasizes the potential effect of city trees on the whole hydrological balance via a combination of field data and simulation experiments using both specialized interception models (Gash and Rutter) and the relatively simple interception module of a holistic water balance model (WetSpa).

“…Direct method need less period but it also needs special instrumentation, hence it costs more [4]. Rainfall intensity, duration of the storm and temporal and spatial variability of trees are few factors that influence canopy storage capacity [6] The objective of this paper was to study the canopy storage capacity for Scindapsus Aureus. Other objective was to investigate the effect of different rainfall intensity on canopy storage capacity.…”

Canopy Interception is one of the vital component in hydrological cycle and underestimating the interception process can significantly affect the water balance. A study of rainfall interception was conducted using rainfall simulator called hydrology apparatus. Three different rainfall intensities were used in this study; 90 mm/hr, 140 mm/hr and 180 mm/hr. These intensities were produced by 8 nozzles. The test were first carried out on the barren land without the existence of canopy cover. To study the effect of canopy cover on canopy storage capacity, broadleaf plant (Scindapsus Aureus) was used to cover the barren land. The differences between the amount of water discharge between these two different land covers were observed to determine the quantity of water stored in the canopy. Results indicated that Scindapsus Aureus intercepted more water at lower intensity than at higher intensity. The lowest intensity was 90 mm/hr stored 1.6mm of rainwater while 140 mm/hr retained 0.8 mm. 180 mm/hr was the highest rainfall intensity used in this study intercepted 0.3mm of total precipitation. Therefore, this study proved that rainfall intensity is one of the main factors that influence the rainfall interception process.

The rapid expansion of impermeable surfaces in cities has a major impact on urban hydrology by reducing rainwater infiltration and increasing runoff rates and peaks. The use of urban trees as stormwater management tools is gaining recognition for their potential to mitigate flood risk and provide additional ecosystem services. We conducted an in‐situ field experiment to measure throughfall on Norway maple (Acer platanoides) and small‐leaved lime (Tilia cordata) to assess the interception capacity of solitary urban trees under different degrees of surface sealing in the city of Freiburg, Germany. We examined the relationships between rainfall characteristics, tree morphological traits, and the interception behaviour, analysing eight trees per species over 76 recorded rainfall events from April to September 2021. Average interception values were higher for small‐leaved lime trees (70.3% ± 6.6%) than for Norway maple (54.8% ± 10.3%) surpassing those in typical forested environments. The average interception loss of all recorded events was 2.6 ± 0.6 mm for Norway maple and 3.7 ± 0.3 mm for small‐leaved lime. For both tree species, significant linear correlations were found between the relative interception and factors such as rainfall depths, the leaf area index (LAI), and the plant area index (PAI) (adj. R2 >0.45). Unlike Norway maple, small‐leaved lime demonstrated significant relationships between several tree morphological parameters and interception (adj. R2 >0.43). The LAI of both species significantly decreased with the increasing degree of surface sealing, which in turn affected interception rates. Our results enhance the understanding of the interception process by solitary trees in urban contexts and enables the parameterization of interception rates using measurable properties. To develop a comprehensive database for modelling parameters and aid urban planners in stormwater management, further field experiments involving various tree species are essential.
