Darcy’s Law

Velocity (v) of flow is proportional to the hydraulic gradient (i). Thus,

V = Ki              (17.1)

where k is the coefficient of permeability (cm/sec) or hydraulic conductivity. If i is equal to one, the v = k. Thus, coefficient of permeability is velocity of water for unit hydraulic gradient. Hydraulic gradient can be expressed as: i = Δh / L , where Δh is the head loss and L is the length between two points (as shown in Figure 17.2).
