Mechanically Stabilized Earth, better known as MSE, is slowly emerging in today's industry as a cost-effective alternative for slope stability and soil erosion control. Among its many variations are gabions with soil reinforcement panels and geotextile cloth, both of which are commercially available already. There has been no record prior to the research, however, that these two have been used together as a shoreline revetment. The thesis group therefore set out to investigate if this particular combination would perform well on its own as an alternative to the commonly used cement retaining walls. Experiments conducted on the settlement of the structure and its rainfall discharge were carried out to observe its performance as well as a Slope Stability Analysis using Bishop's Method of Slices to determine whether or not the MSE wall would produce the highest factor of safety. After simulating 108 cases in a simple model, this combination indeed proved the most stable and safe option, giving off the highest factor of safety while also yielding encouraging results in the experiments. The results and general findings of this study are valuable to the engineering body of knowledge that is constantly seeking for safer and cost effective solutions to make our lives simpler and easier to lead.
