It provides an overview of major types of models applicable to problems in the unsaturated zone of the subsurface. As chemical transport in soils is often driven by the movement of water, both flow and chemical transport models are included. To manage the rapidly growing amount of information, IGWMC maintains a descriptive model information system, MARS (Model Annotation Search and Retrieval System). Detailed information on the reviewed models is presented in a series of tables. 收起
