英文摘要: The accurate estimation of soil dispersivity ( α ) is required for characterizing the transport of contaminants in soil. The in situ measurement of α is costly and time-consuming. Hence, in this study, three soft computing methods, namely adaptive neuro-fuzzy inference system (ANFIS), artificial neural network (ANN), and gene expression programming (GEP), are used to estimate α from more readily measurable physical soil variables, including travel distance from source of pollutant ( L ), mean grain size ( D 50), soil bulk density ( ρ b), and contaminant velocity ( V c). Based on three statistical metrics [i.e., mean absolute error, root-mean-square error (RMSE), and coefficient of determination ( R 2)], it is found that all approaches (ANN,...
