Abstract: In this paper, a coupled system dynamic and water quality model (SD-WQM) was developed to simulate human-nature-compound water system in a rapidly urbanization catchment. The SD model was applied to describe the interactions between socio-economic, water resources, and wastewater system and to predict the population and economic growth, water consumption and water pollutant loads in each sub-catchment; the WQM was applied to describe the pollutant transport and transformation processes and to predict the water quality in a river system. The two models were coupled by distributing the pollutant loads in each sub-catchment to the outlets or confluents along the river. An application to Shenzhen river catchment indicated that SD-WQM is a flexible and consistent method to evaluate the effects integrated measures, which include not only engineering measures but also some socio-economic policies, to achieve resource balance and water quality improvement in a rapid urbanization area.
