ABSTRACT
Recently, one of the biggest challenges in this century is climate change and global warming. The climate change effect has changed that condition from the regular season to be unpredictable season on the word, where the more extreme conditions such as heavy rain falls and droughts. So To find out and well understanding the physical phases of value of cohesion of soil and slope stability due to water infiltration and rising water table in unsaturated soil, we make the several models to fine FoS due to variation of cohesion and variation of inclination by using software Flac3d. And the result illustrated some of FoS in variation of total cohesion and variation of inclination angle for unsaturated condition. Where, deviation of FoS from unsaturated condition to saturated condition has about 13% decreasing on inclination 35o and 16% on 40o
Keywords : climate change, unsaturated soil, cohesion, slope stability, infiltration and rising water table, Flac3
