Description :
Surface runoff and soil loss were studied on skid trails in Nav district (North of Iran) after each rainfall event. Two skid trails were selected in this study. Two levels of slope (10, 31%) and three distances among water diversions (25, 50, 75 m) were applied in three replications. The results confirm that slope steepness is a primary factor in controlling surface runoff and soil loss on skid trails. Therefore, reducing skid trail slope during construction and rehabilitation of these trails is recommended to decrease surface runoff and soil loss in forest operations.
