AB - This study aims to analyze the sedimentary environment change in mid-channel bar of the
lower Geum river basin after the construction of the estuary barrage using multi-temporal
satellite data and GIS. The sedimentary environment changes were observed in mid-channel
bar areas. The mid-channel bar F was found to have been newly formed for 10 years(1996-2006),
whereas the mid-channel bar B located between mid-channel bar A and C has disappeared by
erosion during the same periods. When examined by section, the areas of the mid-channel bar
in the upper stream section from the Yipo’s reference point generally increased due to the
prevailing sedimentary environments, and those of the downstream section decreased where
corrosive environments are dominant. In ternms of the centroid movement, the mid-channel
bars grew up toward the downstream by switching erosion and accumulation, as
sedimentation was prevailing in the downstream area of mid-channel bars and corrosion was
dominant in the upper stream. Through grain size analysis, the study areas are divided into
three sections according to the average grain size. In Section I, the mid-channel bars were
formed as a result of sedimentary process of tides in the past. In Section II, the mid-channel bars
were formed partly through the sedimentary process of rivers although the sedimentary
process of tides is prevailing. In Section III, the mid-channel bars were formed mainly through
the sedimentary process of rivers, even if it showed the sedimentary process of tides in the past.
