One of the major sources of landslide is pore water pressure associated with heavy rainfall. The frequent and heavy rainfalls at Madikeri, India created severe environmental damage due to the landslides. In the present work, the soil in the selected area was analyzed to determine the in situ soil properties and identify the suitable in-situ ground reinforcement technique to improve the slope stability. The slope stability analysis was carried out using GEO5 software tool with five different methods, i.e., Bishop, Fellenius, Spencer, Janbu, and Morgenstern-Price. Four types of ground improvement techniques, i.e., anchors, nails, reinforcement, and anti-slide piles were studied to analyze their suitability and arrangement with respect to the in situ soil properties. The optimum spacings of ground anchors obtained for a slope of 10 m height are 2 m. The soil nails with pullout resistance of 50 kPa and 1 m spacing gave optimal results. The reinforcement with 40 kN/m tensile strength and 1 m spacing shown satisfactory results. The optimal results with anti-slide piles were obtained with 650 mm diameter piles spaced 0.9 at 0.9 m center to center.
