recently, the most important topic in water management was to determine the effects of urban forests and green space on partitioning gross rainfall (gr) into the rainfall interception (i), stemflow (sf), and throughfall (tf). the main aim of this research was to quantify the seasonal variations [growing season (gs), and non-growing season (ngs)]) in i by individual fraxinus rotundifolia trees i...
the main goal of this study was to compare of rainfall interception (i) by pinus eldarica and cupressus arizonica plantations afforested in the chitgar forest park in a semiarid climate zone of iran. from the september 2012 to september 2013, gross rainfall (gr) and throughfall (tf) were collected through 10 and 50 rain-gauges, respectively. i was calculated as the difference between gr and tf....
gross rainfall (gr) partitioning into throughfall (tf), stemflow (sf) and interception loss (i) was studied in a pure oriental beech (fagus orientalis lipsky) forest located in the central caspian region of northern iran. measurements were performed on a rainfall event basis in a 5625 m2 plot of the kheyrud forest research station of tehran university during 2008 and 2009 growing seasons. gr wa...
In water-limited regions, rainfall interception is influenced by rainfall properties and crown characteristics. Rainfall properties, aside from gross rainfall amount and duration (GR and RD), maximum rainfall intensity and rainless gap (RG), within rain events may heavily affect throughfall and interception by plants. From 2004 to 2014 (except for 2007), individual shrubs of Caragana korshinski...
spatio-temporal variability of throughfall (tf) has an important role on the biogeochemical processes,soil, watershed hydrology as well as the nutrient cycle in forests. spatial distribution and temporalstability of tf patterns by five individual persian oak trees (quercus brantii var. persica) in thezagros forests of western iran, ilam, was quantified. sixteen tf manual gauges were placed bene...
This research was carried out in order to quantify throughfall (TF) and interception loss (I) and to compare the chemical composition of TF, i.e. lead (Pb) and cadmium (Cd) as well as electrical conductivity (EC) and pH beneath Pinus eldarica and Cupressus arizonica plantations and the open field rainfall. The research was accomplished in the Chitgar Forest Park, a semi-arid polluted urban area...

we estimated the rainfall interception loss (i), canopy storage capacity (s), the ratio of mean evaporation rate from the wet canopy () over the mean rainfall intensity () (mm h-1) (), and free throughfall coefficient (p) in a fraxinus rotundifolia mill. stand located in an afforested park land in a semiarid region of iran. for each storm event, i was calculated as the gross rainfall (gr) minus...
the aim of this study was to compare rainfall interception (i) in a natural forest of fagus orientalis l. with a neighboring picea abies plantation in kelardasht area, the caspian forests, north of iran. to measure gross rainfall (gr), four manual collectors were installed in an open area adjacent to the forest sites and throughfall (tf) was measured using 20 collectors randomly located underne...
this study aims to investigate value conflicts between mothers and their daughters among families and influential factors on this conflict in yazd city. this study adopted a survey method and a questionnaire was used that its validity through construct validity (factor analysis) and its reliability by cronbach alpha were measured. the population of this study consists of all yazdian families th...
