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.
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.
The term, introduced into geology by McGee (1908, p. 199), is derived from the Latin verb saltare, meaning to jump or leap. Movement by saltation has also been invoked for water transport of particles near the bed (see chapter 10), although the distinctiveness of saltation in water is not nearly as clear as in air.

The term ‘saltation’ describes the process by which sand grains are picked up and transported by the wind. Sand grains bounce along the ground in the wind; when the wind stops or slows down, the sand is deposited and may build sand dunes. An inland line of sand dunes marks a former shoreline near Prestatyn, North Wales. BGS © UKRI. Water.
Bed load sediments do not move continuously. This intermittent movement is called saltation. Streams with high velocities and steep gradients do a great deal of down cutting into the stream bed, which is primarily accomplished by movement of particles that make up the bed load. Here is a video of bedload transport.
