Bagnold formula
From Wikipedia, the free encyclopedia
The Bagnold formula, named after Ralph Alger Bagnold, relates the amount of sand moved by the wind to wind speed. It states that the mass transport of sand is proportional to the third power of the friction velocity. Under steady conditions this implies that mass transport is proportional to the third power of the wind speed at any fixed height over the sand surface. The formula was derived by Ralph Alger Bagnold in his book The Physics of Blown Sand and Desert Dunes and has in wind tunnel and field experiments been found to be basically correct. It was later been modified by several researchers, but is still considered to be the benchmark formula[1][2].
