WebTransport by wind takes place almost entirely within 0.5 m of the ground surface with nearly 90% of this movement within 2.5 cm of the surface (Bagnold 1941). WebIn 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 …
