I am studying on Groundwater modeling. In one part of my work, I need to model water flow in the vadose zone. Does anybody have a MATLAB or Fortran code for solving 3D Richards equation? It is very necessary for me.
Hi, You could try Hydrus-1D, which is a free download: http://www.pc-progress.com/en/Default.aspx?hydrus-1d. It models water flow through the vadose zone in one dimension.
