  • Tidal influence on downstream fining in gravel-bed rivers

    Creator:
    Coles, Derron Rafiq
    Abstract:
    This research examines the downstream fining phenomenon as it operates in coastal gravel-bed rivers of Oregon. Downstream fining is a change in bed composition toward smaller sediment sizes in the downstream direction. Changes in stream flow discharge and channel slope affect the rate of bed-load transport, thereby altering the downstream...

  • Reducing sediment production from forest roads during wet-weather use

    Creator:
    Toman, Elizabeth Myers
    Abstract:
    Forest roads produce fine sediment with traffic during wet weather. If the forest road is connected to a stream it can be a source of turbidity and fine sediment that may be detrimental to aquatic organisms especially salmonids. The goal of this work was to investigate turbid runoff during wet-weather...

  • Consistency and effectiveness of advisory speeds: an evaluation of current posting techniques

    Creator:
    Rohani, Joshan W.
    Abstract:
    Crash rates are said to be nearly three times higher on curved sections than those on straight sections of rural roadways. As a result, advisory curve/speed signs are standard practice to mitigate these risks on sharp horizontal curves. The industry standard for determining appropriate and uniform speeds for such signs...

  • Efficiency of bioswales in positively effecting storm water quality

    Creator:
    Grenz, Natalie S.
    Abstract:
    Because of the increased need for sustainable construction in an ever urbanizing culture, new sustainable drainage systems are being developed and implemented. Bioswales are becoming an increasingly popular form of sustainable urban drainage used for parking lots and subdivisions. But little is known regarding the effectiveness of bioswales in really...

  • Sustainable construction safety and health rating system

    Creator:
    Rajendran, Sathyanarayanan
    Abstract:
    The main objective of this research study is to incorporate construction worker safety and health into sustainable design and construction practices. This can be fulfilled by the development of an innovative construction worker safety and health planning tool, called Sustainable Construction Safety and Health (SCSH) Rating System that will: •...
