The slope stability analysis is always under severe threats in many parts of nilgirisdistrict, causing disruption, loss of human life and economy. The stability of slopes depends onthe soil shear strength parameters such as Cohesion, Angle of internal friction, Unit weight ofsoil and Slope geometry. The stability of a slope is measured by its factor of safety usinggeometric and shear strength parameter based on infinite slopes. In this research, investigationwas carried out at 5 locations in Kattery watershed in nilgiris district. The factor of safety of theslope determined by Mohr Coulomb theory based on shear strength parameter calculated fromdirect shear test which is a conventional procedure for this study. Artificial.Neural Network (ANN) Model is used to predict the factor of safety. The input parameters forthe (ANN) are chosen as Cohesion, Angle of internal friction, Density and Slope angle and thefactor of safety as output. The results obtained in ANN method were compared with that ofconventional method and observed a good agreement between these two methods.
