A statistical approach has been applied in order to evaluate chemical interaction between groundwater and river water by using electrical conductivity (EC) in the Changnyeong-Haman river barrage (CHRB), Korea. The EC values in groundwater have been decreased an average of 50 μS/cm and 160 μS/cm. According to factor analysis using the EC data, the EC in groundwater has been disturbed by the CHRB construction as well as dredging of the Nakdong River during the construction work and with time ealpse the groundwater quality became stabilized. It is also demonstrated that hydrologic environment has been changed due to the CHRB construction, comparing the 1st period and 4th period. Hence, a long-term monitoring is required in order to reveal the change of hydrologic environment that can adversely affect plant growth.
