Follow rain into a lined landfill. Cover, waste layers, geomembrane, drainage gravel, perforated collection pipes and a sump separate collection from leakage.
• 3D scene parts: Cover / surface runoff; waste layers; composite liner; drainage gravel / perforated pipe; sump / extraction pump. • Controls: Landfill area (0.5–5 ha); Rainfall intensity (0–20 mm/h); Runoff / cover exclusion (0–0.95 fraction); Collection capacity (0–100 m³/h); Sump capacity (20–100 m³); Liner defect index (0–1 relative). • Live readouts: Leachate inflow (m³/h); Sump storage (m³); Collected volume (m³); Leakage + overflow (m³). • Guided experiments: Pump unavailable; Defective liner. • Four tabs (visual laboratory, curves and measurements, experiments, learn and assess), a model-verification run, a timestamped event log and a trial report.

Initial sump storage is 10 m³. Immediate infiltration and prescribed leak coefficient; no unsaturated travel time, leachate chemistry or geotechnical liner calculation. Try the preset experiments, then compare the live readouts with the equations.
