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?

Landfills

The landfill is a site used for the disposal of waste materials. The landfill is a solid waste facility that is often known as a dumping ground. The image below shows a landfill site in Hawaii. Landfilling is the most ancient and common method used for the disposal of waste. For the landfill, a deep trench is constructed in an isolated place away from the city. The trench for landfills is designed properly after analyzing the total population and the waste generation per capita. The waste is dumped into the trench and after every layer of waste, a layer of soil is spread on the top of it.
