Impact of Precipitation on the Landslides Activation in the Context of Climate Changes

Landslides are the result of different natural and anthropogenic phenomena. Unfavourable weather conditions in synergy with additional load or relief of the slopes, improperly designed or poorly executed and poorly maintained drainage systems, as well as other anthropogenic causes, significantly affects to the overall stability of the slope. In such unstable conditions, on the slopes are often triggered a landslides that pose a significant threat to critical infrastructure. Weather conditions, such as heavy rainfall, due to the increase of groundwater level and soil saturation are common triggers of landslides occurrence. It's expected that the climate changes in the coming decades cause a significant increase in precipitation. Climate change will result in an increase in air temperature and consequently increase the water vapor content in the atmosphere. Since the 1°C increase in temperature increases the ability to moisture-holding in the atmosphere by about 7%, the potential for more frequent and more intense precipitation events will be significantly higher than it is today. In climate change conditions, soil humidity will also be higher and together with the increase in precipitation will have a direct impact on increasing the number of active landslides. This paper provides an overview of the impact of increasing precipitation on landslides creating, as a result of the expected climate change.
