2D WATER QUALITY ANALYSIS SYSTEM IN HAN RIVER

摘要

Current industrial development and population growth have been caused a rapid increase of wastewater discharge. Also, frequently occurring drought has increased the necessity of an effective water quality control and management of river flows for reserving instream flows. This study attempted to develop a hydrodynamic numerical system composed of a two-dimensional flow prediction model and a contaminant transport model, and to apply the developed system for the scientific water quality control and management in the Han River. This study was to construct a GIS-based river flow system, and it is useful for supporting user's decision making for the on-line status through various analysis.
