Abstract

The characteristics of the suspended sediment transport in the open channel flows with a rectangular dead zone are investigated experimentally and numerically. The properties of the deposition in the dead zone are classified into 4 patterns. The influences of the hydraulic parameters on the deposition patterns in the dead zone are examined through the laboratory test by changing the hydraulic conditions. The deposition processes aresimulated numerically by the plane 2-D flow model. The numerical results indicate that the large scale vortex at the interface promotes the transport of suspended sediment into the dead zone.
