DEVELOPMENT OF EARLY WARNING MODELING SYSTEM FOR SUDDEN CHEMICAL SPILL IN PLAIN RIVER NETWORK
An early warning modeling system for assessing potential river water quality threat from sudden chemical discharge incidents was developed, based on a hydrodynamic model for tidal plain river network equipped with sluice gates and water quality models. For the hydrodynamic model, the mode to simulate river flow under artificial irreversible gate operation was presented, so that the flow related to gate control with tidal occurrence could be simulated, which was calibrated by the measured data. For the water quality models, three kinds of models including oil spill model, hydrophobic model and hydrophilic model were developed based on chemical properties. With China’s Shanghai river network waters as the domain, oil spill scenario and hexachlorobenzene (HCB) spill scenario representing hydrophobic chemical were simulated based on the verified model parameters, and showed the application of the developed early warning modeling system.
