Abstract

It was thus decided to investigate this issue to find a method to protect slope from erosion on this road and to provide new approaches to slope erosion knowledge gap in Sudan. An engineering survey was carried out, followed by geotechnical studies, experimental work and interviews with academic experts regarding native vegetation in the survey area. These include measuring the eroded parts of the road. Studying cross- sections of the road; soil experiments to check the strength, compaction and particle size distribution and a native vegetation survey to check for suitable plants that could be used to control the slope erosion. It was found that an appropriate bio-engineering method to stabilize the slope soil against erosion due to rainfall was to cultivate the grasses Cynodon Dactylon and Vetiver on the slopes. The Wad Medani-Sennar roadside slope connecting the Gezira and Sennar States is a vital transportation corridor that facilitates the movement of goods and people. However, the slope faces challenges related to erosion, instability, and ecological degradation.
