theory of sediment transport

Sediment transport is the process by which particles like sand, silt, and gravel move through water or air. This movement occurs due to forces such as water flow in rivers or currents in oceans, as well as wind in deserts. When the flow is strong enough, it lifts or pushes particles along the bed, carrying them downstream or downwind. The sediment can be transported in different ways: as floating material (suspended load), rolling or sliding along the bottom (bed load), or through a combination of both. This process shapes landscapes, forms river channels, and influences ecosystems.
