“…Canopy interception was calculated from a simple mass balance equation often used to describe precipitation partitioning (Crockford and Richardson 2000;Xiao and McPherson 2002;Toba and Ohta 2005;Herbst et al 2008;Barbier et al 2009;Gerrits et al 2010;Inkiläinen et al 2013;Zabret et al 2016):…”

“…This can be attributed to denser canopy cover in the mixed forest, a substantial assemblage of coniferous evergreen trees (46% in the growing stock) with wider crowns, especially dominant Norway spruce trees, and the highest growing stock (Table 1). Those are all stand structure variables which contribute to higher canopy interception (Toba and Ohta 2005;Dietz et al 2006;Vilhar 2016). Conifers tend to have greater interception capacity than deciduous trees (Inkiläinen et al 2013) and large trees with considerable canopy surface area can decrease throughfall by intercepting a substantial fraction of bulk precipitation (Brauman et al 2010).…”

Urban forests provide important ecosystem services. In terms of hydrological benefits, forest ecosystems in urban environments represent qualitative and quantitative filter for rainwater. We quantified the canopy interception in relation to urban forest stand structure and rainfall intensity in an urban transect of the mixed (upland) forest in the city centre, towards a riparian pine forest and a floodplain hardwood forest in the City of Ljubljana, Slovenia. Bulk precipitation in open areas and throughfall were measured with fixed rainfall collectors in each forest. Stemflow was estimated from a review of relevant literature. We found that canopy interception in selected urban forests was mainly affected by tree species composition and other stand structure variables, such as canopy cover and tree dimensions. Average annual canopy interception was highest in the mixed forest (18.0% of bulk precipitation), while the riparian pine forest had the lowest level (3.9% of bulk precipitation) and the floodplain hardwood forest had the intermediate level for interception (7.1% of bulk precipitation). The mixed forest exhibited the stand structure factors that contributed to the highest canopy interception among the studied forests: high assemblage of dominant coniferous trees, denser canopy cover and the highest growing stock. Furthermore, rainfall intensity has proven to be an important factor for the seasonal partitioning (comparing the leafed and leafless period) of canopy interception. A better understanding of precipitation interception processes in urban forests is needed to assist urban forest managing and planning, aiming at maximizing canopy interception for the mitigation of stormwater runoff and flooding in urbanized watershed.

From 30 January 2011 to 30 January 2012, we measured the rainfall interception (I) and canopy storage capacity (S) of individual trees of Pinus eldarica and Cupressus arizonica planted in the Chitgar Forest Park near Tehran, Iran. Gross rainfall (GR) in this semiarid region was measured using the mean of 6 plastic rain gauges placed in an open area adjacent to the trees. To measure throughfall (TF), 20 plastic rain gauges were installed beneath the crowns of 5 individual trees of each species. I was calculated as GR minus TF. S was estimated using indirect methods: the minimum, Gash and Morton, mean, and Pereira methods. The cumulative mean values of relative percentage of I (I:GR) for P. eldarica and C. arizonica trees averaged 44.2% and 34.4%, respectively. Significant negative relationships were observed between the percent of I:GR and GR for P. eldarica (R 2 = 0.63) and C. arizonica (R 2 = 0.67) trees. For P. eldarica, S was estimated to be 1.10 mm, 1.00 mm, 1.09 mm, and 1.05 mm using the minimum, Gash and Morton, mean, and Pereira methods, respectively. For C. arizonica, the corresponding values are 0.58 mm, 0.52 mm, 0.56 mm, and 0.55 mm. This study proposes that in this climate dominated by small storms, planting C. arizonica is preferable to planting P. eldarica. However, the differences in the transpiration of these species should be quantified. Our results also indicated that the I value in this semiarid climate was higher than that of a humid climate.

“…For example the capacity of a coniferous or a deciduous tree is different, deciduous tree can hold more water in its bucket-like leaves, a coniferous tree can hold much more water by adhesion [11].…”

“…The amount of stemflow is determined by leaf shape and stem and branch architecture [33]. Others studies show that there is a large difference in the canopy interception by deciduous and coniferous trees [9,11,30] because the leaf area of coniferous trees is much larger than of deciduous trees, coniferous trees can store much more water.…”

The hydrological performance of individual tree can be estimated by measuring the stem flow, throughfall and rainfall interception. Water distribution through tree canopy is affected by tree architectural model and another tree's morphology. This research was done in order to predict the most appropriate tree species that is suitable on soil and water conservation. This research was conducted in Purwodadi Botanic Garden during the rainy season on January 2014 to March 2015, in order to examine the interception rate, throughfall and stemflow on some selected local plants i.e Syzygium polyanthum, Diospyros blancoi, Schleichera oleosa, Madhuca longifolia, and Canarium vulgare. Other observation that support the data, was also measured i.e. Leaf Area Index (LAI), crown depth, leaf size, Diameter of Breast Height (DBH), and height of tree on each species. Results showed that Diospyros blancoi has the highest interception value, which is 53 %, followed by C. vulgare 47.4%, S. oleosa 46.9 %, M. longifolia 38.6%, and S. polyanthum 35.6% respectively. Under the heavy rain, D. blancoi, which has the highest LAI value, also showed the best performance in the rainfall interception value and showed significantly different among others. Canopy interception and stem flow is related to rainfall, the higher the rainfall, the higher the throughfall and the stemflow among species. Morphology on each species, gives the different effect on their partitioning rainfall value.Keywords: Throughfall, stemfall, rainfall interception, local trees species, Purwodadi Botanic Garden Recycling hidrology is always spinning at any time, it is strongly influenced by the environment and greatly affect the environment. To better manage the hydrology elements, basic information on the environtment elements and inter-relating effects of them is essential. One of the hidrology elements is rainfall and one of the environtment elements is vegetation.The fall of rain water into the ground can be influenced with vegetation grown around area [1].Interception is part of the rainfall that is intercepted by earth's surface includes everything that becomes wet after a rainfall event and that dries out soon after [2]. It is refers to precipitation that does not reach the soil, but is instead intercepted by leaves and branches of plants and the forest floor [3]. Interception can amount up to 15-50% of precipitation, which is a significant part of the water balance. The interception losses were dependent not only upon the intensity of rainfall events [4,5] but also upon the size of the drops [6], and differences in interception losses among canopy species were explained by the size of throughfall drops [7]. Canopy interception can be calculated by measuring the hydrological performance of individual trees. It can be estimated by measuring stemflow, pass the crown gap (through-fall) and interception of rainwater [3].Vegetation often modifies the intensity and distribution of rainfall by stem flow, through fall, and interception through its leaves and branc...
