Abstract The forest road is most important sediment sours in the forest regions. the forest roads with remove vegetation cover and disorder hydraulic behavior regions, causes sediment product and problems due of sediment. This study has been done to surveying sediment factors roll in the sediment producing in the northern forest road. For this goal were selected purpose road sections by using homogenous unit map (rainfall, aspect slope, hillside aria and geology) in geography information (GIS) and operation studies, in the culverts output selected sections, were created wooden sediment trapping dams. Spearman analyses Results shown then maximum correlation with high cut slope in the sediment product. Also The result of analysis variance and comparing between the average sediment produced in different slope classes showed positive and significant different. with increase of road age and vegetation cover the amount of sediment significantly decreased. The amount of total sediment that evaluated in study area was about 51 ton in year.
