Rolling to steep sand dunes, UAE
This area consists of high relief rolling to steep hills comprising mega barchan dunes with minor pockets of small sabkha plains. The small sabkha plains often contain cemented secondary gypsum accumulation material, more than 10cm thick, at variable depth. The map unit occurs within the Liwa crescent in the southern part of Abu Dhabi close to the Saudi border. Polygons range in size from 69ha to 28,9924ha. The land is used as low-density grazing. The map unit is devoid of vegetation or has a sparse vegetation cover of Cyperus conglomeratus on the dunes slopes together with Zygophyllum and Tribulus spp on the edges of gypsic and salt flats. The map unit forms part of the Cyperetum-Zygophylletum vegetation community.
The soils of this map unit are dominated by Typic Torripsamments, mixed, hyperthermic (90% AD158) in the dunes. Other soils are Gypsic Haplosalids, sandy, gypsic, hyperthermic, aquic phase (5% AD134) and Typic Petrogypsids, sandy, mixed, hyperthermic (5% AD123). Topographic gradient and relative relief are the main constrains to the use of this land for irrigated agriculture.
