This study assesses the behavior of a roadside natural slope along the economically viable 'Marine Drive' project to protect the lives there as well as the safety and security of the human-made infrastructure. However, roads are often severely affected by landslides, resulting in road blockages, damages and recurrent economic losses in developing countries due to the limitations of engineering geological investigations. In the present study, the stability analysis was conducted using different approaches. Initially, the limit equilibrium methods were employed to analyze the large-scale, deep-seated failure. In addition, the numerical technique based on the two-dimensional Finite Element Method (FEM) was also implemented to analyze similar slope sections. For instance, the computer-aided programs SLIDE for LEM, and PLAXIS 2D for FEM were used to draw this comparison. It has been argued that FEM is a more sophisticated tool in modern practices to analyze and predict slope soil's stability and corresponding displacements. Finally, this comparative study aimed to investigate the surface that is most likely to fail, reporting the critical factor of safety of slope on the clayey sand soil condition of that location. Considering climatic variations that result in it being a rainfall-prone hilly area, this particular slope may be subjected to erosion or an increased water level. Therefore, the slope stability soil condition with higher permeability affecting the strength parameters was also assessed along with the variations in slope geometry.
