In ground water flow, the velocity with which a tracer would move is:
1
the same as the seepage velocity given by Darcy’s law
2
\(\frac{1}{n}\)times the seepage velocity where n is the porosity of the formation
3
\(\frac{1}{n}\)times the seepage velocity where e is the void ratio of the formation
4
K times hydraulic gradient (i.e. v = K × i) where K is Darcy’s coefficient.
