Transport of Suspended Material in Open and Submerged Streams
Publication: Journal of Hydraulic Engineering
Volume 111, Issue 5
Abstract
The energy exchange in streams carrying suspended material is analyzed using an efficiency concept. The efficiency is defined as the ratio between the gain in potential energy of the suspended material and the turbulent dissipation. It is shown that the efficiency is not constant, but depends linearly on Shields' parameter. The linear relation is used to develop a simple formula, which describes the suspended load as a function of well‐known parameters. With the results from open streams an auto‐suspension criterion is developed for turbidity currents. This criterion describes the situation when a submerged current carrying suspended material neither deposits nor erodes material.
