Abstract
Chemical spills in surface waters often occur in modern societies, which cause significant impact on water quality, eco-environment and drinking water safety. In this paper, chemical spill contamination in water resources is studied by using a depth-integrated computational model, CCHE2D, modified for predicting fate and transport processes of chemical contaminants in surface waters. The processes of volatilization, photolysis, hydrolysis, adsorption, desorption, degradation, etc. were included, and the interaction between sediment bed and water column were also considered. To simulate the fates and transport processes of chemicals using the developed chemical spill module, many parameters of the chemical materials are needed. A database was developed to provide information for involved chemical processes. Hypothetical chemical spill cases were simulated using the CCHE2D model and the developed chemical property database.
