“…Decision makers can rely on information derived from models to implement the planning and management of water resources. Over the last two decades, environmental fluid dynamics code (EFDC) and the water quality analysis simulation program (WASP) have been used extensively to simulate water quantity and quality in urban rivers, tidal rivers, or estuaries (Hwang and Lung, ; Hamrick and Wu, ; Scaratos, ; Wool et al ., ; Lung and Nice, ; Zou et al ., ; Ji, ; Liu and Huang, ; Luo and Li, ; Jeong et al ., ; Jia et al ., , ; Guo and Jia, ; Xiao and Jia, ). These modeling studies have considered the calculation of capacity, load distributions, water resource scheduling, sediment transport, and emergency responses in areas affected by tidal action.…”

A modeling study was undertaken under a decision support system (DSS) for drinking water security in the Foshan section of the Beijiang River, a typical tidal river in the North Pearl River Delta. The DSS included a database layer, application support layer, and an application layer. As an integral part of the DSS application support layer, an integrated modeling system was developed to simulate hydrodynamics. The balance of dissolved oxygen and toxicants was based on an environmental fluid dynamics code and a water quality analysis simulation program (WASP) modeling framework. Model calibration and validation was undertaken using monitoring data in normal hydrological conditions. Four scenarios for the environmental management of water, including current water temp‐spatial feature analysis, control of pollution sources, and emergency response, were designed and analyzed in the DSS. The results indicated that the tide downstream has a distinct influence on hydrodynamics and pollutant diffusion, and the DSS could be used to design effective schemes to reduce pollutant discharges and provide emergency responses for ensuring drinking water security.
