This tutorial assumes the user desires to include a silt material in an unsaturated seepage model. The user currently has a particle-size distribution and initial volume-mass properties for the soil. The intent is to guide the user through the estimation of a reasonable Soil-Water Characteristic Curve (SWCC) and an unsaturated hydraulic conductivity curve.
In the estimation of unsaturated soil permeability property, the two most important pieces of information required are the SWCC and the saturated coefficient of permeability (or hydraulic conductivity). SVSOILS allows for the theoretical estimation of both of these properties for the purpose of modeling unsaturated seepage modeling.
