Abstract
This paper reports a model for the flow of two incompressible and immiscible fluids in soils, developed by combining a modified Darcy's law with the continuity equations. The resulting equations are of a system of nonlinear partial differential equations. Numerical analysis, based on the finite element method and Newton-Raphson's method, to solve the equations is given and discussed. Computer simulations of the flow of water and trichloroethylene in sands are also shown. © Williams & Wilkins 1987. All Rights Reserved.
