title: LANDFLOW: a 3D finite volume model of combined free and porous flow of water in contaminated land sites.
abstract: Free and porous flow of water in lands often occurs in combination under different physical circumstances. To model such configurations, open and porous flow regions need to be studied independently and also to integrate them through well-posed mathematical formulations. This paper presents a computational investigation (modelling and simulation) on flow of water and contaminants' mobility in soil. The governing partial differential equations of the flow were discretised and reduced to algebraic forms by finite volume method for simulation purposes. Dirichlet boundary conditions were used at the inlet. For sidewalls, no slip conditions were imposed while for the outer boundary, stress free boundary conditions were used.
