A Method for Determining Unsaturated Hydraulic Conductivity of Undisturbed Soil

A new experiment method for determining parameters of soil water movement is put forward, which is that two parameters are determined in the same one experiment. According to the principle of determining undisturbed soil sample parameters, a new device is designed and introduced. Through successive correction of the assumed soil water characteristic curve by iteration method, unsaturated hydraulic conductivity of the undisturbed soil sample is obtained. At the same time, the soil sample is also obtained.
