Aeolian processes are those processes of erosion, transport, and deposition of sediments that are caused by wind at or near the surface of the earth. [1] Sediment deposits produced by the action of wind and the sedimentary structures characteristic of these deposits are also described as aeolian.
Aeolian or eolian (depending on the parsing of æ) is the term for sediment transport by wind. This process results in the formation of ripples and sand dunes . Typically, the size of the transported sediment is fine sand (<1 mm) and smaller, because air is a fluid with low density and viscosity , and can therefore not exert very much shear on ...
Aeolian landforms, or Eolian landforms, are produced by either the erosive or depositive action of wind. These features may be built up from sand or snow , [ 1 ] or eroded into rock, snow, or ice. Aeolian landforms are commonly observed in sandy deserts and on frozen lakes or sea ice and have been observed and studied around Earth and on other ...
Sediment is a solid material that is transported to a new location where it is deposited. [1] It occurs naturally and, through the processes of weathering and erosion, is broken down and subsequently transported by the action of wind, water, or ice or by the force of gravity acting on the particles.
In an aeolian environment, cross-beds often exhibit inverse grading due to their deposition by grain flows. Winds blow sediment along the ground until they start to accumulate. The side that the accumulation occurs on is called the windward side. As it continues to build, some sediment falls over the end. This side is called the leeward side ...
Coastal sediment supply is the transport of sediment to the beach environment by both fluvial and aeolian transport. While aeolian transport plays a role in the overall sedimentary budget for the coastal environment, it is paled in comparison to the fluvial supply which makes up 95% of sediment entering the ocean.

Saltation of sand. 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.
