Slope Stability Analysis of Landslide Susceptible Areas—A Study in the Western Ghats, Kerala
Landslide occurrences are largely controlled by different causative factors. Geotechnical properties of soil viz-a-viz type of soil, density, cohesion, angle of internal friction, hydraulic conductivity, etc. affect the natural stability of slopes, and therefore, these data can be utilized to determine the susceptibility of a slope to landslides. In this project, an attempt is made to analyze the stability of slopes, especially in landslide-prone areas in the Western Ghats, Kerala. For this, three different areas are selected viz-a-viz Alathur, Vennikkulam, and Pananchery in Kerala. These study areas are experiencing repeated slope failures at the onset of every South-West monsoon. With the help of soil data from laboratory experiments, rainfall data of the study area, and slope stability analysis using GeoStudio® software (using SEEP/W and SLOPE/W), the factor of safety of slopes in these study areas is obtained. It is found that Alathur in Palakkad district is more prone to landslides as compared to the other two places. Software modeling can provide analytic frameworks for quantifying and understanding the underlying patterns of landslides under various local conditions. The results obtained from stability analysis are useful in categorizing study areas into different classes based on their susceptibility to landslides. Such a study would be helpful for future land use planning and landslide mitigation in the study areas.
