Indoor experiment on measurement of soil hydraulic parameter using the method without restrict point-source infiltration

Simulation model was used to predict soil water movement processes. The accuracy depends on the accuracy of soil hydraulic properties, thus, it is important to estimate soil hydraulic properties accurately. Without restrict point-source infiltration method was developed based on steady point-source infiltration function, and its accuracy was still not evaluated. In the paper, the steady point-source infiltration experiment was conducted, and the method was evaluated based on the experimental dada. The results indicate that the method can be used to estimate soil hydraulic properties.
