This course is a basic professional course for graduate and doctorial students of environmental profession. Through learning this course, students can understand contaminant transport law in multimedia environmental system, analyze and predict the contaminant transport processes in multimedia environmental system. The course consists of eight chapters. Chapter one is an introduction including basic concept for environment model and simulation, research content and trend of numerical modeling of contaminant transport in environmental media. Chapter two focuses on basic model for contaminant transport in environmental media. Chapter three is contaminant transport models in surface water including river water quality model, estuary water quality model, lake water quality model and reservoir water quality model. Chapter four is contaminant transport models in subsurface water including contaminant transport model in soil, porous aquifer media, and fractured aquifer media. Chapter five focuses on contaminant transport model in atmosphere. Chapter six is contaminant transport model in life body. Finally, chapter eight is numerical methods of contaminant transport model in multimedia environmental system including finite element method and finite difference method.
