Abstract: Surface-water and groundwater systems are in continuous dynamic interaction. Processes such as infiltration from surface waters and precipitation, the discharge of groundwater to surface waters through baseflow, evapotranspiration, and pumping wells create physical responses which are transmitted throughout the surface-groundwater system. Computer models provide the state-of-the-art means to a quantify these interactive processes. A review of six models which address various aspects of the surface-groundwater system was undertaken. These models: MODFLOW, MODFE, SHE, SAMSON, MODSIM, and the UC Davis model were selected to represent a cross section of available models from government, business, and academia. An overview of model development, user requirements, mathematical structure, and field applications is provided for each model.
