| Abstract: | The Streamline Upwind/Petrov Galerkin (SUPG) finite element method is applied to solute transport in unsaturated soils.A numerical expression has been derived and a computational programme has been developed.Calculations have been made for 1 dimensional problems. Calculated results are compared with those of field tests and other numerical methods.The comparison shows that this method is correct and has good stability. |
