  • Comparitive snow accumulation and melt during rainfall in forest and clearcut plots in western Oregon

    Creator:
    Berris, Steven Neil
    Abstract:
    A study was conducted to compare snow accumulation and melt during rainfall in adjacent forest and clearcut plots in the transient snow zone of the western Cascade Range in Oregon. Snow accumulation differences were determined by comparing the water equivalents of forest and clearcut snowpacks. During rain-on-snow periods, energy balances...

  • Hydrology and delineation in four wetlands in the Oregon Cascades

    Creator:
    MacLeod, Norman A.
    Abstract:
    Four wetland sites were identified and delineated in Silver Falls State Park, Oregon using procedures outlined in the 1989 Federal Manual for the Identification and Delineation of Jurisdictional Wetlands and subsequently monitored for a ten month period. A network of 225 shallow (32") wells was installed throughout the sites to...

  • Countersunk culvert hydraulics for upstream juvenile fish passage

    Creator:
    House, Matthew R.
    Abstract:
    Twenty-one countersunk culverts in Oregon were inventoried to establish baseline information for the stream crossings so that subsequent resurveys can assess the long-term stability and functionality of the culvert design. A subset of the inventoried culverts was selected for detailed hydraulic measurements. The detailed velocity measurements were used to help...
