The assessment of sediment production yield from forest road using sediment prediction model

Forest road construction is including high costs as if in operations of road construction the saving be inappropriate thus, it is following more damages. Therefore, this study was performed for estimate of annual sediment mean in a forest road network of forest watershed in southeast of Sari city (North of Iran) using a sediment prediction model with considering to the effective factors. In order to, different data includes: topography, roads and also, precipitation mean were recorded. Result of this research showed that the SEDMODEL model with GIS is appropriate compound for using by road construction managers for prediction of sediment total. This result of it can be used for expansion of road construction in future. © 2008 Asian Network for Scientific Information.
