Hi everyone,
In FeFlow, I just started to model 2D vertical model. I have to model unsaturated flow. I have tabular data for saturation and capillary pressure head, so I will use spline approximation. The problem is I don't have any relative conductivity-saturation data. Before the FeFlow, I used another software which automatically estimates matric suction and hydraulic conductivity curve from saturation and capillary pressure head. It uses Van-Genuchten and Fredlund-Xing methods to draw the unsaturated hydraulic curve from soil water content curve. Does FeFlow do such thing ? If not can you help me how I can calculate relative conductivity and saturation data.
