The slope material consist of thick section of loose soil and fragmented sandstone, due to incessant rainfall for about a week, these weak overburden got saturated and the pore water pressure increased which diminished the available shear strength to a p

• Construction of retaining wall at the toe portion of the slope founded over bedrock/hard sub-stratum with sufficient weep holes.
• Construction of drainage ditches along the road. 
• Easing of the slope by benching.
• Removal of loose debris fr
Cutting of toe for road construction on natural slopes with weak slope forming material disturbed the angle of repose of the material, and heavy downpour resulted in development of local pore water pressure in the weak slope forming material and reduced
