Abstract

To analyze rainwater infiltration into soil and its effect to slope stability, it is important to have an understanding of soil hydraulic properties, in particular the relationship between volumetric water content 0 and soil capillary pressure Ψ, and the relationship between unsaturated hydraulic conductivity K and Ψ. These relationships are known as the water retention curve and the hydraulic conductivity function, respectively. There are many soil water retention-hydraulic conductivity model have been proposed such as Brooks-Corey (BC) and van Genuchten (VG) model that were derived base on empirical fitting curve and log normal (LN) distribution model based on soil pore radius distribution. A numerical model using these three soil-hydraulic properties models was developed to estimate the extent of rainwater infiltration into an unsaturated slope, the formation of a saturated zone, and the change in slope stability. In this study, these three models were compared to analyze the soil moisture, water movement phenomena and slope stability characteristic in a soil slope. The numerical simulation showed that VG and LN models resulted very similar in term of soil moisture content, water movement and slope stability characteristic compared with BC model.
