A large-scale land excavation at the Gimpo terminal of the Ara waterway could cause the changes in groundwater level and quality at the surrounding area. The result of the groundwater level’s forecasting using a numerical model indicates that land excavation and entire draining brought the changes in groundwater level, flow velocity, and its direction and consequently these hydrologic changes produced the variations in groundwater quality controlled by an oxidation-reduction environment. When water-filling at the terminal after a construction completion, groundwater level at the monitoring well becomes recovered in one month, which is similar to the result of a numerical model. High turbidity at some existing wells is estimated to be originated from both a lot of fine minerals in the sediments and the increase in groundwater velocity after an excavation. Diverse investigation and analysis is required before a large-scale excavation to prevent the changes in groundwater hydrology and quality.
