ABSTRACT

Preliminary results of pedogenic investigations on Khor Gomatyawa, in the north eastern part of the Red Sea Hills (Sudan), will be presented in this paper. The main target of this work is the reconstruction of the climatic changes during quaternary for the only region of the Sudan influenced by winter rains. The results of this study indicate that the investigated area has been influenced by three arid periods, separated by two semi arid periods. Through modelling the salt dynamic in the soil the begin of the last arid period was estimated to be about 3000 years ago.
