Osmosis is a special type of diffusion whereby water is moved from an area of high water potential into an area of lower water potential. In principle, the same concepts applyâ¦ for osmosis as it does for diffusion. The particles travel in a concentration gradient without the use of energy.
Dispersion is a process that occurs to all constituents dissolved or suspended in groundwater. Dispersion occurs due to the flow and hence only in flowing water, while diffusion occurs irrespective of whether the water is flowing or not. Solute transport is described mathematically by the advection-dispersion equation:
