Infiltration modeling breakthrough

Fred L. Ogden
We developed an efficient solution method to the one-dimensional partial differential equation (PDE) for unsaturated porous media flow attributed to Richards [1931]. Our solution is a set of three ODE's that was derived by starting from the same equations used to derive Richards' [1931] PDE. We used a change of dependent variable hodograph transformation, employed a finite water-content discretization and the Method of Lines to produce an ODE, which in its various forms accurately simulate...
