Comparison of an unsaturated soil zone model (SESOIL) predictions with a laboratory leaching experiment

Model predictions of a modified version of the soil compartment model SESOIL are compared with laboratory measurements of pollutant transport in soil. A brief description of SESOIL is given and modifications that have been made to the model are summarized. Comparisons are performed using data from a laboratory soil column study involving six chemicals (dicamba, 2,4-dichlorophenoxyacetic acid, atrazine, diazinon, peritachlorophenol, and lindane). Overall, SESOIL model predictions are in good agreement with the empirical data. Limitations of the model are discussed.
