its either on a slip face, crest, windward slope, or any area of a dune
role in formation of sand dunes (in sand dune: Formation and growth of dunes)...sand brought up the windward slope. When this depositional slope is steepened to the angle of repose of dry sand (about 32°), this angle is maintained and the added sand slips down the slope or slip face. When this happens, the dune form is in equilibrium, and the dune moves forward as a whole, sand being eroded from the windward side and deposited on the lee.
The windward side of a sand dune is generally gentler and more gradual, while the leeward side is steeper. This steep slope on the leeward side, often referred to as the slip face, forms as sand is deposited on the windward side and then cascades down the leeward side due to gravity. As a result, the leeward side typically has a more pronounced angle of repose compared to the windward side.
The steep face of a sand dune is called the slip face or the lee side. It is typically located on the leeward side of the dune where the wind direction forces the sand to accumulate in a steep slope. This portion of the dune is constantly shifting and changing due to the interaction of wind and sand movement.
The upwind direction of a sand dune has a gentle slope. A steep slope is on the downwind side. The pronounced slope of a sand dune is called a slip face. Sand erodes from the wind off the slip face. To learn more about sand dunes, visit http://www.tulane.edu/~sanelson/geol111/deserts.htm.

The leeward side of a dune is shorter and called the slip face. Dunes often serve an important purpose in protecting land from storm waves.
A sand dune is a desert feature that forms as a result of wind or rain action towards one side. The sand dune usually forms towards the dominant side of the wind direction and can vary in gradient.
A leeward slope is on the opposite side of a mountain, opposite to where the wind is blowing. For example, wind is blowing from north to south to a mountain, and the south side of the mountain would be the leeward slope.
The steep side of a dune is called the slip face. It is the side of the dune where sand grains are deposited as they slide down due to gravity.
