Beispiele für Wüstentypen (Desert Types of the Western Desert of Egypt):
 
Erosion valleys or wadis (Queds) with vegetation distribution in wadi channels
 

Location: 23°37'N / 26°14'E
23°37'19.40"N / 26°14'46.39"E
Upper part of Wadi Mashi with two lateral channels, or broad runnels respectively. The vegetation is dominated by Fagonia arabica (mainly dead), and Stipagrostis acutiflora (rare, mainly dead), building large phytogenetic hillocks.
 
Location: 23° 8'N / 26° 2'E
23° 8'11.00"N / 26° 2'25.04"E

Deep and long lateral Wadi (not named) of Wadi El-Akhtar with very large phytogenetic hillocks (like elephant head dunes) of presumably Fagonia arabica and Stipagrostis acutiflora distributed as a broad field along the main channel bank. The wadi itself has a width of nearly 700m in this area. This wadi has not been visited. This vegetation was found by evaluation of satellite images.

 
Location: 23°14'N / 26°13'E
23°14'8.71"N / 26°13'46.35"E

Wadi El-Bakht: Transverse dunes are very common in the wadis of the southern Gilf Kebir. Stipagrostis acutiflora grows very often on the shallow lower parts of stabilized dunes, where this species can cover large areas. Generally, Stipagrostis prefers Cambic Arenosols. Fagonia arabica is dominating the wadi edge, channel banks, and in smaller wadis central parts with Haplic Yermosols, Eutric Regosols, but also Cambic Arenosols.

For more information on Soil-Vegetation relationships in the Gilf Kebir, compare:
