Abstract
Water Quality Model System(WQMS) is an important approach to analyzing aquatic situation and supporting environmental decision. However, the usage and promotion of WQMS is largely limited by amounts of parameters, complex conditions and enormous operations. A GIS integrated system of urban water environment coupled with SWMM (storm runoff model), ECOM (hydrodynamic model) and RCA (water quality model) was constructed in this study, with the production and transformation of contaminants in large scale taken into consideration. This integrated system guaranteed an independent calculation and multi-model coupling calculation, including convenient pre-processing, fast and efficient model running and results visualization in different spatial and temporal scales, in the purpose of simplifying the usage and promotion of complex models and providing necessary understanding required in water resource managing and water pollution controlling, and ultimately improving decision making capability. The functionality of the proposed system was illustrated by a case of Wuhan city.
