It occurs when loose materials are removed from a bed and carried by the fluid, before being transported back to the surface. Examples include pebble transport by rivers, sand drift over desert surfaces, soil blowing over fields, and snow drift over smooth surfaces such as those in the Arctic or Canadian Prairies.

Jun 27, 2021 · The term saltation is used for a mode of particle movement in which trajectories of particles show take-off from the bed at moderate to steep angles and descent to the bed at small angles. Figure 9.4.1 9.4. 1 shows a typical saltation trajectory taken by a saltating grain of sand in air.
: Traction - large, heavy pebbles are rolled along the river bed. This is most common near the source of a river, as here the. load. is larger. Saltation - pebbles are bounced...
Feb 19, 2022 · Saltation occurs when particles are suspended in the stream for a short distance after which they fall to the bed, dislodging particles from the bed. The dislodged particles move downstream a short distance where they fall to the bed, again dislodging particles upon impact.
Saltation: This involves slightly heavier, coarser particles such as sand and gravel. They are too heavy to be continuously suspended but too light to remain on the riverbed. Instead, they ‘hop’ or ‘bounce’ along the river bed, lifted by the water’s flow and then settling back down.
The characteristic mode of motion of sand particles in air is saltation: particles are launched from the bed, take arching trajectories of widely varying heights and lengths, and splash down onto the bed at low angles, commonly rebounding and/or putting other particles into motion.
Saltation – where small pieces of shingle or large sand grains are bounced along the sea bed. Traction – where pebbles and larger material are rolled along the sea bed.
