1. If the landfill had a compacted density of 600 Kg/m3 a refuse depth of 9 m (29.5 ft), a moisture content of 20% by volume, and a 1-m (3.25-ft)-thick clay cover with a 2% slope, estimate:
(a) The quantity of leachate that would be generated each year.
(b) How long it would be before each year's deposit of refuse is saturated and leachate flows from that section? Use rainfall and evapotranspiration values appropriate for your area.
