Palaeoflood study using the slackwater deposits in the dong river, korea

Song Hyun Kim, Yukiya Tanaka

Research output: Contribution to journalArticlepeer-review


Slackwater deposits have been used in numerous studies to estimate the magnitude and frequency of discrete flood events. Study area is located along the Dong-river in Gangwon province, the east of Seoul, Korea. Caves are formed along the both the Dong-river banks. The results of grain-size analysis suggest that grain size (median, ø) of each layer changes according to flood events. The age of slackwater deposits by flood may be estimated more exactly based on relative age methods through the trash and the data of river water level and absolute age methods through the radioisotope 137Cs. It is able to estimate the frequency and magnitude of palaeoflood using these results such as grain-size analysis, stratigraphical description and several dating methods.
