The purpose of the study was changed of Flood Characteristics in Down stream of Keum River by the Keum River Estuary Dam Construction. The water surface slope of Kuem river after the Keum River Estuary Dam construction was steeper then before. The flood control capacity increase after construction. But, Increasing sediment in Kuem river will be decreased flesh reservoir volume for yield irrigation.

Physical and acoustic properties of sediment on the southwestern Taean Penisula, the Yellow Sea, were studied using eight piston cores. The sediments in the study area are largely composed of sand which has been deposited with sea-level change after LGM(Last Glacial Maximum). After the sea-level rise, fine-grained sediments discharged from Keum River and neighboring coast area were deposited as muddy sand or sandy mud. Results of these sedimentary environment in this area, the texture of sediments are different from place to place with variable horizontal and vertical distribution of physical and acoustic properties. Correlations among the physical, geoacoustic properties, and mean grain size show slight deviations from those of the South Sea in spite of similar pattern. This is probably due to the differences in sedimentary environment, mineral composition, and measurement system.
