Green Roofs for Flood Reduction and Prevention

Model type : Rooftop structures
-
Flood prediction and numerical simulation research discusses about rain absorbtion ability of green roofs, and proposes how to effectively reduce flood through green roofs, to contribute to researches and policy related to green infrastructure.
Green roofs absorb rain by planting plants on the rooftop. It is used throughout Europe as it's space-friendly and relatively easy to use.
 
Green areas reduce as urbanization proceeds. Reduction of green area destroyed vegetation, which decreased amount of rain getting absorbed from soil, raising risk of flood. Green roofs were installed to reduce risk of flood in urban areas.
 
Plant plants on roofs to absorb rain, and utilize soil moisture data to trace relationship of precipitation and efflux.
 
Efflux can be calculated through initial soil moisture or precipitation, which allows across-the-board application regardless of precipitation and plant types.

Planning

- Efflux can be calculated using precipitation and soil moisture data
- Thickening middle layer, and flatter soil moisture can reduce flood damage
