Water Allocation by Weighting Factors Considering Multiple Criteria

초록

Typically, water has been allocated by some priority criteria in each country like water rights. However, water allocation by the priority might have the problem which the area of a lowest priority can be suffered from water shortage all the times. So, this study has tried to develop water allocation rules by weighting factor techniques. The weighting factors are estimated with sectoral and regional factors. The AHP (Analytic Hierarchy Process) is applied to estimate the sectoral factors. And the regional factors can be divided by the regional-characteristic and regional-scale ones. The water allocation rules for the reservoir are developed by applying those weighting factors and the rules are applied to Andong dam reservoir which supplies the water to Busan-Si, Daegu-Si, and Goryeong-Gun, Korea in water deficit situation. As a result, all sectors and regions could share the burdens of water shortage by the water allocation using the relative weighting factors.
