Landfill Cell Designer

Size a landfill cell as one system: sloping floor, clay liner, waste prism, and cover. Stormwater, leachate, gas, and liner-interface stability all follow from that geometry — Civil Web Kit.

Cell cross-section

Drag sliders to change floor slope, liner, and waste height. Stability uses waste on the liner interface, not an independent weight.

Liner-interface Fs: 1.32

Stormwater peak Q: 0.194 m³/s (C i A / 360)

Leachate: 85 mm/yr

Methane q: 9.274e+5 m³/yr

Liner breakthrough: 3 yr

Waste mass: 305810 Mg · excavation (indicative): 1040 m³

What to look for: Fs below 1.5 as waste height or floor slope rises; stormwater Q scaling with area and C; breakthrough growing with liner thickness and falling with k.
