Figure  2  shows  the  average  transport  velocity  of  the  leachate  which  was  calculated  by  dividing  the  Darcy  flux  by  the  effective  porosity  of  the  porous  medium
Figure 9 depicts how the pollutant concentration gradients ( 3component) vary  in the landfill at 10 days interval as the pollutant is continuously added at the near  boundary  at  a  constant  concentration
Figure  12  is  an  isosurface  of  contaminant  concentration  within  the  porous  medium
Figure  13  shows  that  the  concentration  gradient  (total  or  vector  sum  of  the  three3dimensional values  of concentration gradients) is lowest at the point where  the  concentration  is  highest,  (at  around  0.14  m  along  the  3axis)  and  th
