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.
Saltation - pebbles are bounced along the river bed, most commonly near the. source. . Suspension - lighter sediment is suspended (carried) within the water, most commonly...
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.
noun. a dancing, hopping, or leaping movement. an abrupt movement or transition. Geology. intermittent, leaping movement of particles of sand or gravel, as from the force of wind or running water. Biology. a sudden, drastic genetic mutation or series of mutations occurring between one generation and the next, especially one that generates a new ...
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, in the context of geography, refers to the transportation of small particles, such as sand or gravel, by wind or water. These particles are lifted up and then fall back down, moving in a series of short leaps or bounces.
