Daily cells for a landfill are operated so that the following conditions are maintained: thickness of daily cover= 0.2 m; slope (horizontal:vertical)= 3:1, working face for refuse= 30 m; height of refuse= 3 m; and volume of daily refuse= 1,800 m^3/day. The landfill is interested in reducing requirements for daily cover soil over its 20 year life and is considering three options (that is, have a lower Vs/Vr). Which option should be the best? Why?

Question

 Daily cells for a landfill are operated so that the following conditions are maintained: thickness of daily cover= 0.2 m; slope (horizontal:vertical)= 3:1, working face for refuse= 30 m; height of refuse= 3 m; and volume of daily refuse= 1,800 m^3/day. The landfill is interested in reducing requirements for daily cover soil over its 20 year life and is considering three options (that is, have a lower Vs/Vr). Which option should be the best? Why?
Option 1: Increase height of refuse to 4 m.
Option 2: Increase daily refuse volume to 2000 m3/day.
Option 3: Decrease working face to 20 m.
