In order to take into consideration the two dimensional infiltration (2-D) of water in furrows, the performance of Warrick two dimensional model was compared with Kostiakov-Lewis, Philip, and advanced HYDRUS-2D models. The accuracy of different methods was evaluated by comparing the measured furrow infiltration that was computed by input-output method. The results indicated that the 2-D Warrick model had the least error and Philip model had the highest error among the model tested. The absolute error (AE) and RMSE of the two dimensional Warrick infiltration model were obtained as 5.5% and 0.0031 m3 m-1 respectively. The absolute error of the Kostiakov-Lewis and Philip were 20.2% and 25.5% and their RMSE were 0.0042 and 0.0058 m3 m-1 respectively. Also the results showed that the difference between the two dimensional Warrick infiltration and the HYDRUS-2D models was 3.5%.
