Evaluation of Optimal Amount of Groundwater Development for a Rural Small Watershed

농촌 소규모 유역의 지하수 적정개발량 평가

The purpose of this study was to obtain optimal amount of groundwater development for a rural small watershed. The optimal amount of groundwater development in this experimental watershed is 13.8 %($0.67{\times}10^6m^3$) of the annual rainfall by SCS-CN method. The Visual MODFLOW analyses showed the optimal amount of groundwater development were 14.9 %($0.72{\times}10^6m^3$) of the annual rainfall.
