| Abstract: | The streamline upwind/ Petrov-Galerkin (SUPG) finite element method is applied to solve the unsaturated flow problem. A numerical expression has been derived and calculations have been made for the 1-dimensional Richards Equation. The calculated result of an example shows that this method has good accuracy, convergency and stability. |
