Abstract
The climatic conditions around the world have recently changed, causing many disasters worldwide, including slope instability. This is a result of the amount of precipitation that damages the slope's safety factor, especially the one that is located near a water reservoir, for instance, a river or a lake. Despite the fact that Kazakhstan is one of the world's permafrost countries that has less precipitation than tropical regions, with approximately 39.000 rivers spread across the nation, many slope failures are possible each year. The main objective is to study the suction effect on slope stability in Kazakhstan. The data were collected from available geotechnical investigations, and numerical analysis were done using SEEP/W and SLOPE/W. To conclude, when compared to the slope model without taking suction into account, the slope model with suction consideration displays a higher factor of safety (FoS).
