Abstract

In this study, not only the increase in rainfall for a short period of time but also the increase in rainfall for a longer duration is frequently occurring according to climate change. Changes in rainfall patterns due to climate change are increasing damage to steep slopes. The Ministry of Public Administration and Security has been operating the criteria for evacuation of residents in steep slopes since 2015. However, the damage to steep slopes due to torrential rains in 2020 has been increasing. In this study, rainfall data from areas affected by steep slopes from 1999 to 2020 were collected and compared with the existing criteria(2015) for evacuation of residents at steep slopes of the Ministry of Public Administration and Security, and the status of the issuance of resident evacuation forecast was compared. Through this study, the rainfall criteria for each region were calculated and presented by reflecting the rainfall characteristics of the steep slope destruction area due to climate change, and it is believed that it can be used as a standard rainfall to reduce human casualties in the steep slope area in the future.
