| Zusammenfassung |
| In Korea, a number of over-pumped aquifer has been appeared by numerous human factors that adversely impact groundwater aquifers and lead to depletion of water resources. Especially, Water Curtain Cultivation (WCC) system has a significant role in groundwater management in shallow aquifers of riverside during winter period.
In this study, we studies freshwater extraction by pumping wells to numerically simulate a problem involving groundwater drawdown in Cheongweon pilot area in South Korea. The Cheonweon site has been vastly investigated by previous studies that recorded daily temperature, total discharge by extraction, the number of running wells and the locations. It was recently proved that the number of running wells corresponds to the daily minimum temperature. However, insufficient record for hourly pumping time of each well prevents a good match of simulation results to the field record. The object of this study is to perform an optimization technique with a set of constraints to estimate the relationship between the pumping time and the daily temperature of the site. Finally, simulation results by MODFLOW with optimized pumping schedule is compared with records of several monitoring wells.
