This study was conducted in Maroon riparian forests in Behbahan, Khuzestan province and aimed at calculating interception loss of a pure natural stand Populus euphratica in leafless and in leaf periods. Fifty plastic collectors (9 cm in diameter and 20 cm in height) were placed in a 10 meter grid layout in the studied stand to collect the throughfall (TF). Stem flow (SF) were measured for nine trees belonged to three DBH classes of 10-15, 15-20, and 20-25 cm. In the present research 20 rainfall events (eight in the leafless period and 12 events in the leaf period) were recorded. The value of accumulative rain depth was 218.3 mm. Our results indicated that the percent of SF, TF and I were two, 53 and 45 total rainfall during the in leaf period and three, 62 and 35 during the leafless periods. We showed that large amount of precipitation cannot reach forest floor and The SF and TF had an increasing trend with increasing rainfall. Against, interception showed a decreasing trend with increasing rainfall. We revealed that larger trees produced higher amount of SF. Also, SF production in P. euphratica stand cannot be ignored in the water balance.
