Korea has historically suffered several floods due to heavy rains, typhoons, and heavy snowfalls. Most of the flood damage was caused by storms and tsunamis caused by typhoons, and floods.

Significant flood events and records of flooding in Korea are cited in the detailed paper published July 2017 and authored by Yong Kyun-Kim and Hong-Gyoo Syon and published by the Disaster Preparedness and Coordination Division, Ministry of Public Safety and Security, Sejong, Republic of Korea and the School of Civil and Environmental Engineering, Yonsei University, Seoul.

"..regarding flood damage, there were 178 records in total, indicating that flood damage occurred 0.8 times annually on average. Therefore, it can be inferred that the former part of Joseon Dynasty suffered from drought and flood damage every year.."

'There were 46 records of flood damage including the torrential rain in Busan City on July 12, 1912. Among them, the biggest damage took place in 1920, 1925, and 1936. The heavy rain in Sancheong-gun, Gyeongsangnam-do, on July 19, 1920 poured 400 mm of rain, and the water level of Samnangjin-eup reached 8.09 m, which was the highest water level ever recorded to that time. Accordingly, 37,829 ha flooded and 21,482 ha of land was lost or buried. In addition, 7170 private houses were lost and collapsed and about 1100 people died. Four consecutive severe floods, called the Eulchuk severe flood, occurred in 1925....In 1934 and 1936, several severe disasters triggered by heavy rain occurred consecutively.'^[1]
