Sediment Transport and Deposition Environmental

Sediment transport is the movement of organic and inorganic particles by water 10. In general, the greater the flow, the more sediment that will be conveyed. Water flow can be strong enough to suspend particles in the water column as they move downstream, or simply push them along the bottom of a waterway 11.
