Abstract

The aim of this research was to quantify the seasonal variations in RAINFALL INTERCEPTION (I) by individual ash trees (FRAXINUS ROTUNDIFOLIA Mill.) during growing season (GS), and non-growing season (NGS) in Chitgar forest park located in the SEMIARID CLIMATE zone of Iran, near Tehran. From September 2012 to September 2013, gross rainfall (GR) and TF were collected through 6 and 12 rain-gauges, respectively, in an open area and under the tree crown. RAINFALL INTERCEPTION was calculated as the difference between GR and TF. Fifty rainfall events were recorded and the cumulative GR was measured 156.0 mm. Over the study period, GS, NGS and I ranged 19.4%, 23.0%, and 16.2%, respectively. Significant positive correlations were observed between I and GR over the study period (r2= 0.780), GS (r2= 0.743), and NGS (r2= 0.903) (p<0.01). During the measurement period, GS, and NGS, the percentage of the relative interceptions (I: GR) % were estimated to be 46.6%, 49.3%, and 41.6%, respectively. T-test suggested that there were significant differences between the (I: GR) % values within GS and NGS (p<0.01). It is important to select species trees with lower I values for plantation, since they increase the higher amounts of net rainfall (NR) in semiarid and arid regions where water availability is a limiting factor for plantations growth. Transpiration as well as litter interception of selected trees should be also considered.
