hydrodynamic dispersion

   1. The spreading (at the macroscopic level) of the solute front during transport resulting from both mechanical dispersion and molecular diffusion [22].
   2. The dynamic dispersion of fluid particles in flow through a porous medium due to velocity changes in the pore channels [16].
