The expansion of riparian vegetation in middle size rivers in Korea had been analyzed in this study. Seom River with dam, Cheongmi River without dam, and Naesung River with no operating dam in the upstream was investigated for the 1 km to identify the expansion of riparian vegetation through the aerial photograph analysis. As a results, we found that the rate of vegetation area is 54.7% in Seom River, 77.5% in Cheongmi River, and 49.7% in Naesung River. The vegetation area had been increased in 3 rivers, and the expansion rate since 2010 is very high nearly up to 2 times (17 times in Naesung River). Sandbar and open-water area, however, have been decreased in the same rate with the riparian vegetation expansion. It could be concluded that vegetation increase trend is clear in rivers regardless of location and dam existence. Further researches are necessary to find out the causes to establish the countermeasures because the increase of vegetation will change the physical system as well as biological system of river.
