Study Notes
Chulalongkorn University Centenary Park
- The park in Bangkok is designed to mitigate urban flood risks by collecting, treating, and holding water, able to hold up to a million gallons of water during heavy rainfall.
- The park features a 5,200 sq.m. green roof, capable of irrigating the park for up to a month and storing rainwater in three underground tanks.
- Excessive runoff from the green roof flows through four constructed wetlands, aided by native water plants, and the retention pond doubles in size during severe flooding, allowing visitors to use stationary water bikes to keep the water aerated.
- The park includes eight diverse outdoor classrooms, herb gardens, meditation areas, playgrounds, and an earth amphitheater, paying attention to detail in complementing the park's ecological features.
- 300 varieties of plants and trees have been grown to recreate a healthy ecosystem, following the concept of growing urban forests.
- The park also features a 1.3-kilometer road revamped to prioritize pedestrians and cyclists, with corridors of rain gardens providing shade and reducing runoff from the road surface.
