- 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.

Saltation – small pebbles and stones are bounced along the river bed; Traction – large boulders and rocks are rolled along the river bed. The load carried this way is called bed load. Processes of transportation by a river. The video below shows the movement of sediment in a river.
In geology, saltation (from Latin saltus 'leap, jump') is a specific type of particle transport by fluids such as wind or water. It occurs when loose materials are removed from a bed and carried by the fluid, before being transported back to the surface.

Figure \(\PageIndex{1}\) shows a typical saltation trajectory taken by a saltating grain of sand in air.
Figure 2 of Owen, 1964.) A distinction is commonly made between saltation, whereby particles take ballistic excursions well above the bed, and surface creep (also called impact creep or reptation), whereby particles are moved for short distances without losing contact with the bed surface.
What Figure 11.3.2 shows is that when a saltation layer is present the profile of wind speed in the region above the saltation layer is still logarithmic, but with a significant modification: profiles for different shear velocities no longer converge on the point (0, y0) located on the y axis (where u = 0) but, approximately, on a point (u′ o, y...
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.
