Determination of Hydraulic Properties of Unsaturated Soil via Inverse Modeling
Original language description
The method for determining the hydraulic properties of unsaturated soil with inverse modeling is presented. A modified cone penetrometer has been designed to inject water into the soil through a screen, and measure the progress of the wetting pressure head readings are analyzed to obtain estimates of the hydraulic parameters describing K(h) and 0(h). Optimization results for tests at one side are used to demonstrate the possibility to evaluate either the wetting branches of the soil hydraulic properties, or the wetting and drying curves simultaneously, via analysis of different parts of the experiment. The optimization results are compared to the results of standard laboratory and field methods.
