The sand is coming!
Liwa Oasis, UAE. Sand sheets are relatively flat, undulating plots of sand. They form approximately 40 percent of aeolian depositional surfaces. Sand sheets exist where grain size is too large, or wind velocities too low, for dunes to form.
This region lies in the south of the Emirate adjacent to the Rub
al Khali. It comprises rolling to steep high mega-barchan dunes with broad intervening valleys that have frequently been graded and developed for irrigated agriculture. Occasionally interdunal depressions are deflated to the capillary fringe resulting in saline sabkha flats.
