Abstract

Abstract:
The aim of this research is to recognize the impact of water erosion on agricultural lands deterioration at Wadi Haseeb, Khartoum State, Sudan. The research applied many approaches suitable for geomorphologic studies, such as the descriptive historical approach, the statistical quantitative approach and the survey approach. The research concluded that water erosion is the main factor behind agricultural lands deterioration in the area, and that such deterioration had led to low production and low productivity of agricultural lands in Wadi Haseeb and accordingly, sizable numbers of farmers had abandoned their farm plots as the total numbers of agricultural plots had decreased to less than 50% of the total agricultural lands. indicating that the basin is experiencing an early maturity stage indicating the super activity of water erosion. The research recommends that the water quantities received by Wadi Haseeb should be utilized in water harvesting projects during the dry season and that area should be subjected to more précised, and specialized research in the geomorphological domain.
