This study investigated about the seasonal variation and spatial distribution of pollutant loads flowing into the Jinhae bay. The annual average river discharge in Jinhae bay was estimated about 3,918×103㎥/day for 2 years(2003 and 2004) by Tank model which is the simulation model to evaluate the daily river discharge. The daily average of COD, SS, TN and TP inflowing into Jinhae bay were estimated 9,048.8㎏-COD/day, 1,848.3㎏-SS/day, 2,204.8㎏-TN/day and 288.4㎏-TP/day for 2 years(2003 and 2004), respectively. The largest amount of pollutants are flowing into Masan bay according to the spatial distribution of pollutant loads.

본 연구에서는 광양만 수질환경의 체계적인 관리방안을 마련하기 위한 기초적 연구로서 광양만의 유입부하량과 수질의 계절변동을 파악하였다. 광양만의 수질환경특성 분석에 의해 광양만을 8개의 해역으로 분할하였고, 강우-유출 모형인 Tank model을 사용하여 일별 하천유출량을 산정한 결과 광양만으로 유입되는 2006년 연평균 하천유량은 11,679.42×10³ ㎥/day로 산정되었다. 광양만의 총 유입부하량은 397,789 ㎏-COD/day, 2,845,855 ㎏-SS/day, 195,283 ㎏-TN/day, 5,007 ㎏-TP/day, 125,916 ㎏-DIN/day 그리고 2,763 ㎏-DIP/day로 산정되었다. 앞서 산정된 결과들을 종합하여 분할된 광양만 해역의 물질체류시간을 산정한 결과 갈수기시 각각 6 days-COD, 20 days-TN, 195 days-TP로 산정되었으며, 홍수기시에는 각각 3 days-COD, 6 days-TN, 21 days-TP로 산정되었다. In this paper, in order to setup the management system of water quality environment in Gwangyang Bay, seasonal variation of inflowing pollutant loads and water quality was studies. The Gwangyang Bay divided into eight sea area by Cluster analysis and characteristics of water quality. And river discharge in Gwangyang Bay were estimated 11,679.42×10³ ㎥/day by Tank model. Inflowing pollutant loads of COD, SS, T-N, T-P, DIN and DIP in Gwangyang Bay were estimated 397,789 ㎏-COD/day, 2,845,855 ㎏-SS/day, 195,283 ㎏-TN/day, 5,007 ㎏-TP/day, 125,916 ㎏-DIN/day and 2,763 ㎏-DIP/day, respectively. Finally, residence time of COD, T-N and T-P in Gwangyang Bay were calculated 6 days-COD, 20 days-TN, 195 days-TP, respectively in dry season, and 3 days-COD, 6 days-TN, 21 days-TP, respectively in flood season.

In this paper, in order to setup the management system of water quality environment in Jinhae Bay. inflowing pollutant loads were estimated. Inflowing pollutant loads of COD, SS, TN, TP, DIN and DIP in Jinhae Bay were estimated 148,181 ㎏/day. 1,218,715 ㎏/day. 56,315 ㎏/day. 1,915 ㎏/day, 46,756 ㎏/day and 1.172 ㎏/day. respectively in flood season and 27,763 ㎏/day. 143,787 ㎏/day. 6,195 ㎏/day, 845 ㎏/day. 6.518 ㎏/day and 748 ㎏/day, respectively in dry season. Estimated pollutant loads were more than results of Cho. et al.[1998] in flood season but were lower than those in dry season.
