WebDispersity definition: (uncountable) The state of being dispersed , of being a dispersion. . WebDispersion in porous material refers to the spreading of a stream or discrete volume of contaminants as it flows through the subsurface. For example, if a spot of dye is injected into porous material through which groundwater is flowing, the spot will enlarge in size as it moves downgradient.
WebApr 1, 2009 · Aqueous dispersivity is a phenomenon by which a solute moving in groundwater mixes with water that does not contain the solute and becomes diluted. Solutes take paths of varying lengths through pore networks or experience slower velocities due to interactions with pore walls. Aqueous dispersivity leads to breakthrough curves with … WebEstimated Longitudinal Dispersivity.

WebDispersion is a process that occurs in soils that are particularly vulnerable to erosion by water. In soil layers where clays are saturated with sodium ions ("sodic soils"), soil can break down very easily into fine particles and wash away. This can lead to a variety of soil and water quality problems, including: WebDispersivity definition: An empirical property of a porous medium that determines the characteristic dispersion of the medium by relating the components of pore velocity to the …
WebBy definition, if the system is advectively-dominated (the systems we will consider in this Unit), the molecular diffusion coefficient can generally be ignored (as it is much smaller than D). D is often approximated as: where α is the (longitudinal) dispersivity (dimensions of L). The dispersivity is often treated as scale-dependent.
