The stability of the slopes was governed by the soil’s and/or rock’s hydro-mechanical properties. Present study employs the literature to explore the influence of the hydro-mechanical conditions on the stability of slopes subjected to static and seismic loading conditions. The work examines how hydro-mechanical features like rainfall intensity, duration, hydrological hysteresis, permeability, porosity, slope geometry, and material properties impact slope stability under static and dynamic loading. The effect of spatial and temporal heterogeneity of these factors was also considered to imitate real field scenarios. The FE models in this literature review are calibrated with field data to ensure accuracy and relevance in field-scale modelling. This dual approach allows for a detailed analysis of the triggers for slope failures in varying soil conditions, from fully saturated to unsaturated states. The project’s initial phase was developed as a 2D model, with subsequent plans to extend the framework to a 3D analysis. This work aims to enhance the predictive accuracy and reliability of assessing slope stability under complex and varied hydrological and loading conditions, providing valuable insights for the design and safety assessments of slopes in seismically active regions.
