    Origin Of Sand Dunes. The origin of sand dunes is very complex but there are three essential prerequisites (1) An abundant supply of loose sand in a region generally devoid of vegetation (such as an ancient lake bed or river delta) (2) a wind energy source sufficient to move the sand grains and (3) a topography whereby the sand particles lose their momentum and settle out.

    A cross section or profile of a dune in the direction of blowing wind shows a gentle slope facing the wind and a steep slope to the leeward. A wind shadow exists in front of the leeward slope which causes the wind velocity to decrease. The wind blows the sand grains up the gentle slope and deposits them on the steep leeward slope.

    Sand dune any accumulation of sand grains shaped into a mound or ridge by the wind under the influence of gravity. Sand dunes are comparable to other forms that appear when a fluid moves over a loose bed such as subaqueous "dunes" on the beds of rivers and tidal estuaries and sand waves on the continental shelves beneath shallow seas.
