Abstract : Slope stabilization designs that include soil bio-engineering methods are gaining traction. As a result, researchers have started paying more attention to how plants affect soil strength, specifically how they affect root reinforcement. It has been shown that rural mountain regions in the wet tropics and subtropics are at great danger of erosion, which in turn causes frequent landslides. The use of plant resources to improve slope stability was shown to be more practical than technical alternatives. In many cases, bioengineering technology is employed all over the world since it is an inexpensive method of preventing surface erosion. We conducted experiments to uncover the true potential of these plants for improving slope stability and decreasing soil erosion. Researchers examined the pull-out resistance of the roots and the soil reinforcing potential of the plant roots by growing plants in pot culture and collecting soil samples from the root zone of mature plants. Both direct and indirect measures, including those using image processing, were used to determine the Root Area Ratio (RAR). The collected information was used to examine the effectiveness of root reinforcement and the stability of an artificial slope (a landfill). Finite Element modelling using data from field and lab investigations revealed that having roots on a slope increased the factor of safety by approximately 100%.
