| Abstract: | In order to clarify the infiltration characteristics of the soil at different locations in the field at Hetao Irrigation District,the infiltration process of the soil at different locations in the experimental area were analyzed based on the soil infiltration model to fit the infiltration process.The results show that infiltration characteristics of soil at different locations are closely related with its physical and chemical properties;the infiltration rate of the head of border is 1.42 and 1.81 times of that of the middle and the tail of border,respectively.The infiltration coefficient and the stable infiltration rate show the change characteristics of the head of the border>the tail of the border>the middle of the border,and the cumulative infiltration volume and the initial infiltration rate show the change characteristics of the head of the border>the middle of the border>the tail of the border.The results also show that Horton model simulation parameters have a smaller deviation from the measured values,and is suitable for describing the soil infiltration process in the field. |
