Understanding the soil in the unsaturated state means, among other things, understanding how the presence of water transiently affects the physical and hydraulic properties of the soil environment. This is extremely important in solving soil resistance problems involving water, such as the stability of land slopes. Among the hydraulic properties that are essential in understanding water flow in porous media, flow velocity and soil water retention capacity are the most important defining characteristics of the hydraulic behavior of the medium. In the physical model used in this study, these characteristics were represented by the advective velocity and hydraulic diffusivity parameters that were obtained from the infiltration data by conducting tests on the latosol columns. The main results obtained can be used for the estimation of the wetting front advance given the uncertainties of the variables obtained from the confidence envelope curves. |
