Abstract
In this study, methodology to determine optimal location of washlands based on economic analysis is presented. Install costs of washlands are calculated by construction cost and land compensatory cost and benefits of washlands are calculated from flood damage reduction and befit from using washland as wetland. Indirect approach for runoff-flood damage relationship is suggested and benefit-cost analysis is used for economic analysis. Economic analysis is added to existing models that used only flood reduction effect to determine optimal location of washlands. Suggested methodology is applied to 13 potential washlands in Anseong River basin to examine its applicability. Applied result of new methodology is compared with that of existing model. As the application results, it is possible to determine the optimal combinations of washlands can provide more economic benefit compared to existing studies. It is determined that considering economic analysis can be better option for decision making problem searching for optimal location of washlands.
