This study was conducted to evaluate water quality utilizing principal component analysis in the Nakdong River Estuary. From the results of analysis, water quality in the Nakdong River Estuary could be explained up to 65.3 percentage by three factors which were included in river loading(wastes from the Nakdong River and rainfalls ; 39.1%), sediment resuspension(13.7%) and metabolism(12.5%). In the eastern part of estuary in flowing the Nakdong River, river loading factor score(factor 1)was higher than that in western part. Sediment resuspension factor score(factor 2) was high in shallow water, while metabolism factor score(factor 3) was high in deeper water. For seasonal variations of factors score, factor 1 was highly related to rainfall season.

The reorganization of systems and legal enactments for cultivation of the water industry by the government has led to requirements for local water industry promotion plans. Busan already holds infrastructure for water industry growth including Gijang seawater desalination facilities, and thus the following regional specialization strategies of water industry in Busan has been proposed based on foreign & domestic political trends as well as regional conditions. The global water industry and market is dominated by major water industries. While seawater desalination field only holds great potential for future growth, Korea has competitiveness in terms of engineering competency in the field. Therefore, the strategic measures must be established to promote the local water industry. 1. Improvement of administrative support system for water industry promotion A integrated water management organization must be structured in connection to the enactment of the fundamentals of water management act. Departments including water policy, waterworks, public sewerage, and a integrated water management bureau must be newly established 2. Establishment of Bukyeong Water Resources Corporation Establishment of Bukyeong Water Resources Corporation through formation of local government unions in the Busan and Gyeongnam To find a solution to the problem of securing alternate new water resources through the formation of win-win partnership with 3. Condtruct of a seawater desalination cluster The facilities that exceeded supply of the industrial water would be utilized by test bed and the additional site would be constructed to attract cluster facilities (experiment, education, incubation)
