Climate change and global warming have had an influence on the features of heavy precipitation over the Korean Peninsula. Many researches based on observations have found that the intensity of rainfall becomes more powerful; on the other hand, the number of rainfall days becomes less. It means that the possibility of occurrence of heavier precipitation event becomes even higher in the recent century. This tendency has also shown in this study which investigates the time-series of rainfall amount and the frequency of rainfall in the 21th century. In addition, we emphasize the technique to predict accurate rainfall information because it has been difficult to get reasonable rainfall information in the river basins due to climate change. The flood information system introduced here seems to be useful for the management of water system.
