Title: Wind Erosion in Khartoum State
Author: Farah, Adel Mahgoub
Abstract: The study is about wind erosion in Khartoum State, Khartoum is one of areas affected by land degradation, and the main process of land degradation in Khartoum State is wind erosion. The main objective of the study is: generation of broad-base quantitative actual and potential data on wind erosion in Khartoum State. Four locations were selected: South, West, East and North Khartoum State, with three sites in each location: bare, sheltered, and cultivated fields, West Khartoum a Qoz field is selected instead of cultivated field. Vertical and horizontal wind traps were used with different heights and distances. The study showed the potential wind erosion of cultivated field in order of North Khartoum South Khartoum East Khartoum. The study showed inverse relationship between the height and the intensity of wind erosion, intensity of wind erosion decreases in order of 0 cm > 5 cm > 20 cm > 50 cm heights, intensity of wind erosion increases in order of May > April > March > February > January > December > November. Intensity of wind erosion in order of bare field > sheltered field > cultivated field. Data of the soil surface layer 0 – 30 cm properties analyzed for 1975 and 2002 showed the coarse, fine sand and silt were increased from 22, 13, and 20% to 24, 18, and 26% respectively, while the clay decreased from 45% to 32% for the bare field in South Khartoum. The study showed inverse, and linear relationship between distance and intensity of wind erosion according to the location and the site. The study showed the soil readability of Khartoum State in order of North Khartoum > South Khartoum > East Khartoum. The study showed wind erosivity in Khartoum State in order of February > April > January > March > November > December
