| Abstract |
An intergrated water-quality management system for Masan Bay has been developed using ArcView GIS with a system language Avenue. A water-quality model is linked with environmental databases in the system. The model WASP/EUTRO5 for eutrophication analysis of the bay is included within the system. The databases are mainly composed of data for land use, watershed information, concentration and flow of inflowing pollutants due to runoff, and concentration for water-quality items of seawaters and sediments. The system runs on a personal computer under the Windows environment and provides extensive Graphic User Interface(GUI) for user-friendly assessment. The graphic include a site map and plots of model results such as spatial and temporal variations of pollutants in seawater. Using the pull-down menus provided by the GUI panel, the user is able to operate the system by pointing and clicking the icon to identify the state of water quality at locations concerned. As this system utilized the water-quality model and can predict the current and future state of water quality, it could serve as a useful tool for the decision means of policy-maker |
