Significance of Surface Eco-Protection Techniques for Cohesive Soils Slope in Selangor, Malaysia

Rapid infrastructure development in Malaysia especially in Selangor causes drastic change in landscape and clearing of more vegetated areas. This has gradually lead to slope instability problems that causes enormous loss affecting human lives, destruction of property and environment. Thus, conservat...
