Abstract The rainfall kinetic energy equation derived in the USA has been used in South Korea to quantitatively estimate the amount of soil erosion caused by rainfall for the past 40 years. It is critical to analyze the characteristics of rainfall kinetic energy that causes soil erosion from measured storm events in the study area because the characteristics depend on climate, region, and time. The purpose of this study is to analyze the characteristics in Seoul, South Korea, and the data of the Parsivel rain gauge measured in Seoul for 3 years was used for the current study. This study focuses on deriving the relationship between rainfall kinetic energy and rainfall intensity among the data measured by the Parsivel. The new rainfall kinetic energy equation in Seoul is proposed and compared with the previous equations used in South Korea.
