Advection
Ground water contaminants move in part because the ground water is moving. In many cases advection is among most important factors determining the rate of contaminant transport. The advective terms in the transport equation are

The travel time calculation is limited, however, because dispersion also has a role to play. Dispersion causes some of the contaminants to arrive sooner and some to arrive later than determined by advection alone.
