Abstract
In this study, a two-dimensional depth-averaged chemical fate and transport model was developed and validated as an important assessment tool. The CCHE2D model is a depth-averaged two-dimensional hydrodynamic model, which has been demonstrated to be a robust and efficient tool to simulate flow in natural rivers, reservoirs and lakes. Its capability has been expanded to predict the fate and transport of toxicants recently. The physical and chemical processes in chemical spill are simulated in the model, including absorption, desorption, evaporation, hydrolysis, photolysis, biodegradation, and etc. The interaction between the water column and sediment bed is considered as well. The model's capability to simulate the fate and transport of chemicals was validated by a case of accidental chemical spill in the Rhine River on Nov. 1, 1986 which caused massive fish kill. CCHE2D simulation has shown good agreement in comparison with previous researches (Wanner et al. 1989, Reichert and Wanner, 1987). The model's capability is further demonstrated through a hypothetic case in a reservoir assuming the similar accident happened.
