| Abstract | Rainfall-induced slope failures are one of the most damaging natural hazards in the world. Climate change has resulted in, excessive and unpredictable rainfall especially in mountainous regions which results in landslides with disastrous consequences to human lives and infrastructures. Such problems could be overcome by examining causes for such slope failures and suggesting effective repair plans at these locations by considering future climate change. The results of seepage analyses which was conducted using SEEP/W model demonstrated that the pore water pressure within the fill slope was significantly increased due to the increase of the infiltration during the wet season in 2013. In addition to that in the period of 76 years from 2014, it shows that the amount of precipitation is getting higher in the future in both RCP 4.5 and RCP 8.5 emission scenarios. Results of future slope stability which was obtained using SLOPE/W model for above-mentioned emission scenarios depicts that tieback anchors and geogrids could be effective in increasing the stability of the slopes to an acceptable level during the wet season. |
