Abstract: Cut and exploitation methods used in forest trees affect hydrologic properties. In this study, clear cutting effects on runoff rate is performed in a 2100 m2 area and a similar plot is selected beside it as a control plot. Then the rate of runoff was measured during two consequent years within different temporal stages. Mann-Whitney tests were used for the comparison of two groups which was significant and non-significant in the first and second years, respectively. The results of correlation test also showed that the height of runoff in cut plot is higher than the control plot. In the second year, the rate of runoff in cut plot became closer to the rate in control plot because of herbal plants growth so the results were not significant while in the first year, the rate of runoff increased because of plant cover remove.
