Teh aquifer diffusivity (a) was estimated by using analytical method in order to evaluate river-aquifer interaction, in the riparian zone of the downstream of the Nakdong River located in Changnyeong area, South Korea. The unit step response function suggested by Singh (2004) was applied for determining a. Rainfall impact on groundwater levels was removed by learning algorthms (Yoon et al., 2013) during wet season (July = September) from 2011 to 2014, As a result, a was estimated as 120,000 m2/hr that is approximately equal to an average river resistance of 4,750 m in 2011, 9,150m in 2012, 6,900 m in 2013, and 10,500m in 2014. this result show that the influence of river water level on groundwater level was weakened due th the deposition of fine sediment on the river bed and clogging effect on the observation wells since th construction of river barrage. |
