A clay liner at the bottom of a swine lagoon is 30 cm thick and has a saturated hydraulic conductivity of 10-7cm s-1. If the lagoon is filled to an average depth of 3.0 m and the pressure head immediately below the clay liner is -50 cm, what can you expect the steady seepage rate through the liner to be?

Answer #1

Here we assume that the reference elevation for zero gravitational head is placed at the bottom of the liner.

Then we have the equation for seepage through the liner as:

  

  
= -1.26 x 10^-6 cm/sec
