| description | The study presents a theoretical derivation of a new pick-up probability formulation for
sediment transport. Sand particles are assumed to be subjected to a hydraulically rough
flow. The derived equation compares well with the experimental data found in published
literature. Using the proposed relation, the Shields criterion for the definition of the
threshold condition for sediment transport is equivalent to 0.6% of the pick-up probability. |
