  • Field and laboratory strength analysis of a forest road in NW Oregon and its association with the formation of ruts

    Creator:
    Bord, Andrea J.
    Abstract:
    A one-mile section of a newly constructed forest road in Northwest Oregon was analyzed for various aspects of subgrade and surface strength and their association with the formation of ruts during the first hauling season. Field and laboratory tests were completed on the road and the road materials to determine...

  • A characterization of road hydrology in the Oregon Coast Range

    Creator:
    Gilbert, Erin H.
    Abstract:
    Forest roads alter hillslope hydrologic processes by intercepting, concentrating, and rerouting storm runoff. Current road drainage guidelines are based on minimizing erosion and do not take into account the impact of forest roads on hillslope hydrology. This work monitors ditch flow and rainfall for 10 road segments over the course...

  • Hydrology of five forest roads in the Oregon Coast Range

    Creator:
    Marbet, Christine Erica
    Abstract:
    Understanding the impact of low volume road networks on forested watersheds is important for future forest management and watershed restoration. This study characterized the hydrology of five segments of forest road in the Oregon Coast Range. Rainfall, infiltration, road surface runoff, and intercepted subsurface flow were measured at each road...

  • Influence of log truck traffic and road hydrology on sediment yield in western Oregon

    Creator:
    Miller, Rebecca H.
    Abstract:
    An understanding of the factors that influence surface erosion from roads is necessary to prevent and mitigate sediment production from forest roads. This study investigated the impacts of log truck traffic and road hydrology on sediment yield from ten forest road segments in the foothills of the Cascade Mountains of...
