Bottom friction and bedload sediment transport caused by boundary layer streaming beneath random waves

Myrhaug, Dag / Holmedal, Lars Erik / Rue, Håvard

AbstractThe effect of boundary layer streaming on sea bed shear stresses, as well as on the mean bedload sediment transport rate, beneath random waves, is investigated. Formulas for the bottom friction and bedload sediment transport under regular waves have been applied to obtain the mean bedload sediment transport rate caused by steady streaming under linear random waves. Friction factors for steady streaming under random waves are also provided. The effect of streaming and second order wave asymmetry on the mean bedload sediment transport rate is discussed.
