please can you answer this question

2. The liner for a MSW landfill is constructed on a slope of 6% with maximum horizontal distance of 40 m. According to the HELP model, the average inflow rate is estimated to be 7 mm/day. The hydraulic conductivity of the drainage material is 14 m/day. Compute the maximum leachate head over the liner (in mm) using the following four methods: Moore's 1980, Moore's 1983, Giroud's 1992 and McEnroe's 1993. Show all your steps. 3. Estimate the total amount of LFG generated during the 20-year post closure period of a closed MSW landfill. Soil daily covers occupy about 19% of the total landfill volume. Assume favorable conditions (6.5m of LFG per metric tonne of waste) and 73% extraction efficiency. Assume waste density is 700 kg/m. 21 ml 30 m P=7004 60 m
