| Abstract: | In tropical and sub-tropical slopes, soil suction may in certain circumstances play a role in maintaining slope stability. Resistance envelope methods are outlined that provide a means of assessing the threshold soil water conditions for stability. In addition, this technique enables the likely failure depth to be identified. Application to slopes in St. Lucia, West Indies, show the accordance of resistance envelope predictions with stability analysis results. A methodology for the geomorphological investigation of stability processes in tropical slopes is proposed. |
