# Implementation of Climate Change Effects on Slope Stability Analysis
## 5 Conclusions  
The article presents part of the research work on the importance of geotechnical analysis of climate change adaptation related to slope stability. The objective of this study is to de-termine the effects of expected climate change on geotechnical structures and slopes and their causal relationships. In this article it was chosen to address slope instability, which is the main problem and could be due to increasing precipitation. Therefore, a parametric study of the effects of climate change on slope stability is presented. Moreover, previous studies have shown that slope stability is the most important climate change impact [2]. The aim is to propose guidelines to consider the importance of climate change for planned new structures and for existing geo-structure sand slopes. The case study presented the landslide located in Slovenia, triggered in 2021. The stability analysis was performed considering the theory of rainfall infiltration. It has been shown that the stability of the slope was already low without extreme precipitation, but the slope was stable. In the case of extreme precipitation, taking into account the current extreme precipitation, the slope becomes unstable on the third day of extreme precipitation, which corresponds to the described situation and also more to the predicted precipitation in 2050. The net infiltration of water, was identified as the most critical factor for stability. The analysis clearly shows that timely reduction of net water infiltration through planting and proper surface water runoff from the upper road and slope would be a fairly simple and cost-effective measure compared to the cost of landslide remediation. The analyses also show that measures to reduce net infiltration of water would ensure long-term stability, even considering expected climate change. The importance of climate change to slope stability is determined through a sensitivity stability analysis of the slope. Climate change as expected future extreme rainfall events are important because they affect the net infiltration of water into the slope. Conditions of water permeability and groundwater flow in the slope are important. Conditions of water permeability and groundwater flow are important. When soil permeability is low, the fac-tor of safety for rain events on subsequent days decreases. When permeability is higher, safety decreases more rapidly. The effect of reduced cohesion is nearly linear, with the factor of safety decreasing by almost 0.1 for every 1 kPa less cohesion. Precipitation causes water net infiltration, depending on conditions of evaporation, transpiration, and surface water runoff. In conjunction with climate change, the increase in net infiltration of water may be the most critical factor in slope instability. The results of the analysis indicate that adaptation measures have to be implemented for the presented example of geological and geotechnical conditions of the slope. These can often be achieved quite simply with the planting of trees and shrubs and with well-regulated surface water runoff, which is usually a low cost compared to the cost of landslide removal. Therefore, it makes sense that in the future all slopes should be analysed according to the expected climate change, taking into account climate change, similarly to the procedure shown in this article. The parametric study presented shows that the water infiltration has a great influence on slope stability. Therefore, further research is needed to accurately determine the water in-filtration by incorporating land-climate interactions such as air temperature, relative hu-midity, wind speed, solar radiation, snowmelt, and vegetation. Further research is also proposed to evaluate the effects of increasing soil water content on reducing soil cohesion.
