In this paper, the numerical simulation was carried out to discuss the field measurements to identify soil moisture parameters. In the case where the field measurements will perform every ten minutes, soil moisture parameters can be identified appropriately using the field measurements for around one day. Moreover, the field measurements without rainfalls is available to identify them.
