Application location and role of LID facilities at sponge airport
| Measures . | Location . | Function . |
|---|---|---|
| Biological detention | Soil area in the flying area; green space around parking lots; the construction area of the work area | Infiltration and purification of rainwater; reduce peak and total rainfall runoff |
| Grass planted ditch | Drainage ditch in the flying area | Rainwater conveyance and purification of water quality; reduce flood peak and reduce runoff |
| Rainwater bucket | Specific location in flying area; near the rainwater pipe of the terminal building | Save and reduce the total discharge; staggering drainage |
| Permeable paving | Maintenance area; freight area road | Extending the time of runoff and achieving in situ infiltration; reducing total discharge volume |
| Concave green space | The soil area in the flight area; around the square and parking lot; the building area of the work area | Purifying rainwater; in situ infiltration; accumulation of stagnant surrounding rainwater |
| Impounding reservoir | The way along each catchment area; terminal reservoir | Storage; purifying rainwater; reduce the total discharge volume; staggering drainage |
