Bedload Transport, Self Acceleration, Downstream Sorting, and Flow Dynamics of Turbidity Currents

The experiments reported here are performed in configuration to test the concept of an internal delta. Dissolved salt is used as a surrogate for the finer phase, and lightweight plastic particles are used as a surrogate for the coarser phase. The plastic particles are carried mostly as bedload. Succession sustained flows are allowed to create a deposit behind a barrier that simulates the downstream end of a minibasin. The flows are introduced in the supercritical regime; the downstream barrier forces an internal hydraulic jump to the subcritical regime. This chapter concentrates on (a) the flow pattern created by the barrier and (b) the evolution of this flow pattern as the bed evolved morphodynamically. The documentation of the internal delta itself is given in a companion paper. (Abstract shortened by UMI.).
