13 Facts About Sediment transport
2.
Knowledge of sediment transport is most often used to determine whether erosion or deposition will occur, the magnitude of this erosion or deposition, and the time and distance over which it will occur.

3.
Aeolian sediment transport is common on beaches and in the arid regions of the world, because it is in these environments that vegetation does not prevent the presence and motion of fields of sand.
| FactSnippet No. 2,301,090 |
4.
Sediment transport moved by water can be larger than sediment moved by air because water has both a higher density and viscosity.
| FactSnippet No. 2,301,091 |
5.
Coastal sediment transport takes place in near-shore environments due to the motions of waves and currents.
| FactSnippet No. 2,301,092 |
6.
Sediment transport entrained in glaciers often moves approximately along the glacial flowlines, causing it to appear at the surface in the ablation zone.
| FactSnippet No. 2,301,093 |
7.
Sediment transport is applied to solve many environmental, geotechnical, and geological problems.
| FactSnippet No. 2,301,094 |
8.
Knowledge of sediment transport can be used to properly plan to extend the life of a dam.
| FactSnippet No. 2,301,095 |
9.
When suspended sediment transport is increased due to human activities, causing environmental problems including the filling of channels, it is called siltation after the grain-size fraction dominating the process.
| FactSnippet No. 2,301,096 |
10.
Formulas to calculate sediment transport rate exist for sediment moving in several different parts of the flow.
| FactSnippet No. 2,301,097 |
11.
Bed load Sediment transport rates are usually expressed as being related to excess dimensionless shear stress raised to some power.
| FactSnippet No. 2,301,098 |
12.
Peter Wilcock and Kenworthy T A in their article recognized that a mixed-sized sediment bed-load transport model using only two fractions offers practical advantages in terms of both computational and conceptual modeling by taking into account the nonlinear effects of sand presence in gravel beds on bed-load transport rate of both fractions.

13.
The proportion, as a function of sand content, physically represents the relative influence of the mechanisms controlling sand and gravel Sediment transport, associated with the change from a clast-supported to matrix-supported gravel bed.
