IEFFECT OF SEEPAGE ON SEDIMENT TRANSPORT IN CHANNELS

摘要

Understanding the behavior of sediment beds is important to Earth scientists, Civil and Marine Engineers. The behavior of sediment beds can be influenced by seepage flow through the sediment bed and seepage can sometimes cause structures to fail. This paper deals mainly with an experimental investigation into the effect of seepage on sediment bed load transport and bed forms. Experiments were conducted in the Civil Engineering Department of the University of Liverpool. The object was to obtain bed load transport rates for flows with, and without, seepage. The effect of seepage on the shape of the resulting bed forms was also studied. In addition, detailed velocity-distributions were obtained using an Ultrasonic Velocity Profiler.
