| Abstract |
The objective of this paper is to estimate the reduction rate of pollutant loads from pollution sources using the three dimensional eco-hydrodynamic model for effective water quality management of Masan Bay that was designated as a special management area. COD distribution of the bay was mostly over 3㎎/L. this value exceeded the seawater quality criteria Ⅲ. Total loads of COD, DIN and DIP from point sources were 15.532.5, 11,107.6 and 440.9㎏/day. respectively. A pattern of simulated residual current was dominated by southward flow at surface level. The calculated results by ecological modeling were in fairly good agreement with the observed values. It was evaluated that reduction of total polutant loads from point sources by over 60% is required in order to keep the level below 3 ㎎/L in COD which is the aiming seawater quality criteria of Masan Bay. |
