ABSTRACT
One aspect within the scope of the special research project "Geoscientific Problems of Arid and Semiarid Areas" is to investigate the climate induced development of landscape and soils in NE-Egypt and NE-Sudan. Geomorphologically and geologically the Red Sea Hills region of Sudan can be divided into three units: the flat coastal plain with mainly Quaternary deposits; the mountain chain of the Red Sea Hills rising up to 2.200 m a.s.1., which belongs mainly to the juvenile pan-African basement of the central nubian shield; and the intracontinental plateau built up of crystalline precambrian basement. The mountain chain of the Red Sea Hills forms a natural climate border between winter-rain and summer-rain influenced areas. Two investigation sites have been selected for the interpretation: one soil profile in Wadi Gumatreb and one profile near Wadi Baraka. Wadi Gumatreb is a side wadi of second order within the large Wadi Oko-system.
