Discharge velocity
Short answer
Discharge velocity is the volume of water flowing per unit time per unit gross cross-sectional area of soil, v = Q/A = k i. It is an imaginary average velocity because flow occurs only through voids; the actual seepage velocity is v_s = v/n.
What is discharge velocity?
Discharge velocity (superficial or approach velocity) is the quantity of water flowing per unit time per unit gross cross-sectional area of the soil, taken perpendicular to the flow:
It is an average, imaginary velocity, since water flows only through the voids. The actual velocity in the pores (seepage velocity) is .
