An unsaturated soil water flow equation is studied.A conservative form for the flow equation is established by using upwind finite volume element method.The error estimate of a fully discrete upwind FVE solution with form of O(Δt+h) is obtained.Numerical simulations demonstrate efficiency of the scheme.
