6.3.2 Groundwater Flow and Solute Transport Equations

Fully saturated groundwater flow based on the water balance and Darcy’s law can be described by Eq. 6.2:

(6.2)

where is the specific storage capacity of the porous medium, is the hydraulic gradient, t is the time sec, K is the hydraulic conductivity , and q is a general source/sink term . The velocity of water moving through a flow field described by Eq. 6.3 is shown here:
