The study performs the economic analysis to evaluate the efficiency of buyout land project comparing to the conventional levee project. The cost of buying the potential flood prone area which is identified according to the designated design flood and is compared to the cost of the corresponding levee project. The main stream of Nakdong river between Hwang river and Nam river confluence was chosen as a case study area because those area are prone to the 200 year flood and the land is mostly inexpensive crop field. As a conclusion we proposed that the buyout land project is more efficient than the levee project in an economic viewpoint. Although the study analyzed under certain circumstances and focused on the economic efficiency, it is necessary our object of decision making has to be shifted to the flood prone area not on the river itself.
