Modelling a rock profile

Post by hydrogal » Wed Jan 09, 2019 3:49 am


I am wondering how I would go about modelling a rock profile? I am doing a project with Hydrus and my professor suggested using the van Genuchten parameters, but are those only for soils? I'm trying to model rock profile with a highly fractured layer on top a lower-fracture layer on the bottom.

I suggest that you look at some recent literature on this topic:

Hlaváčiková, H., V. Novák, and J. Šimůnek, The effects of rock fragment shapes and positions on modeled hydraulic conductivities of stony soils, Geoderma, 281, 39-48, doi: 10.1016/j.geoderma.2016.06.034, 2016.
