Fluid flow in porous media using image-based modelling to parametrize Richards' equation
Image-based modelling is used to investigate the relationship between the pore structure and the parameters
Abstract
The parameters in Richards’ equation are usually calculated from experimentally measured values of the soil–water characteristic curve and saturated hydraulic conductivity. The complex pore structures that often occur in porous media complicate such parametrization due to hysteresis between wetting and drying and the effects of tortuosity. Rather than estimate the parameters in Richards’ equation from these indirect measurements, image-based modelling is used to investigate the relationship between the pore structure and the parameters
