Until 1993, Nanji landfill has been the main solid waste treatment facility for Seoul, which is the capital of Korea. Since the landfill has not been properly lined, soil and ground water around the landfill has been contaminated. Due to the proximity, it has been speculated that the water quality of the Han River would have been also influenced by the leachate. In order to illuminate this, HELP model to estimate the quantity of the leachate from Nanji landfill and RMA model to simulate the change of water quality in Han River were applied in this research. The result indicates that the quantity of leachate from Nanji landfill has been overestimated by previous works arid it was due to the failure to consider the water storage capacity of the landfill. The effect from Nanji landfill leachate on the water quality, in terms of COD input, proves to be smaller than those from other tributaries and influents to the River and the effect is larger when the flow of the River is reversed due to the tide.

This paper presents a novel method to predict a flushing rate in an embayment system, which can be utilized to assess an environmental impact caused by harbor construction. The method was successfully applied to the Ulsan-Onsan coastal area. The flushing rate was computed on the basis of water quality changes predicted by US Army Corps of Engineers' RMA-2/RMA-4 models. After calibration and verification to the measured tidal elevation and current velocity, the model was used to estimate the flushing rate in the proposed harbor. The water quality was simulated for 96 hours and the flushing rate was computed. The results indicated that the proposed harbor would significantly reduce the flushing rate in the Onsan harbor, especially at the small embayment area near the south breakwater. The flushing rate was evaluated for several alternatives, of which the tidal flow channel of 1,000 m² in the south pier appeared to be the best mitigation measure. This study proposes that the prediction of flushing rate would be a novel method to assess a water quality impact caused by harbor construction.
