  • A comparative study of the vertical structure of near-bed sediment transport in air and water.

    Advisor: W. Brian Dade

    May 2010

    The vertical structure of mass and momentum within a layer of sediment transport immediately above a bed of loose grains underlying channel flow is observed in both air and ware using high-speed digital videography. Particles examined in this study rand in median...
