Abstract：In order to verify the applicability of one dimensional algebraic model in brackish water irrigation of severe saline-alkali soil, one dimensional infiltration experiments are conducted in laboratory on saline-alkali soil with different levels of mineralization degree(2, 3, 4 and 5 g/L). The model parameters are decided by means of experimental relationships between infiltration rate and wetting front as well as cumulative infiltration. Then infiltration time history and moisture content of soil profile are simulated numerically with the model. The root mean squared error(RMSE)and the index of agreement(D)are chosen to evaluate the applicability of the model. The results show that all the RMSE of infiltration time is less than 6.7 min; all the D produced by infiltration time model is more than 0.99. All the RMSE of water content is <3.5%; all the D produced by water content model exceeds 0.90. This suggests that one dimensional algebraic model can effectively describe the infiltration process of severe saline-alkali soil, this model also can simulate water distribution in soil profile more accurately after an infiltration ends.
