The riverine wetlands located in the riverside bring about social conflicts through confrontation between flood control value through
flood control project and ecological preservation value of riverine wetland. In this study, we identified the importance of both values
through analysis of economic feasibility of flood control and ecological values of riverine wetland, and tried to suggest management
plans for riverine wetland considering both of flood control safety and ecological preservation through these results. For this, we
calculated the expected annual flood damage of Imjin River using the multi-dimensional flood damage analysis(MD-FDA), and
calculated the total value of riverine wetland using the contingent valuation method(CVM) to estimate preservation value of riverine
wetland. The result of the analysis shows that the Imjin River needs flood control project and the ecological preservation of riverine
wetland is also important. Therefore, the establishment of the management plan for protecting riverine wetland is also needed. As a
result, the Imjin riverine wetland was classified as the area where sedimentation continues to take place, and the flood water level to
rise. On the basis of the analyzed results, it is judged that the Imjin River needs flood control for public safety and ecological
consideration for ecosystem preservation in the river improvement project. So, the stepwise river improvement is desirable to protect
riverine wetland and minimize ecosystem disturbance. The results is expected to be made good use as the basic study for
establishment of institutional river management plans considering flood control project and riverine wetland preservation in the future.
