ABSTRACT

The construction of weirs in Nakdong River has altered the farming methods and cultivated crops of the surrounding farmland and the conflict among residents is increasing due to the opening of weir gates. In this study, the characteristics of groundwater fluctuations in the surrounding area due to the opening of the Hapcheon-Changnyeong weir gate were analyzed, focusing on the area of Gaekgi-ri, Ugok-myeon, Goryeong-gun in Gyeongsangbuk-do. The simulation scenario was based on the river water level, recharge characteristics, and the conditions for groundwater use. In all scenarios, it is found that the groundwater level was determined according to the level of Nakdong River and some groundwater levels changed by the characteristics of quarterly recharge characteristics and groundwater use conditions. This study found that fluctuations in the groundwater level in the upstream region are inevitable due to the gate opening of Hapcheon-Changnyeong weir and problems in groundwater use could occur in some areas with shallow groundwater facilities.
