F2 - SEM1 - The Trouble of Water - 6.1 Flashcards
In China, why the water cycle changed in the past few decades?
6.1 How has the water cycle in China changed in the past few decades
rapid urban development since 1980
6.1 How has the water cycle in China changed in the past few decades
In China, how does rapid urban development affect water cycle?
6.1 How has the water cycle in China changed in the past few decades
increase the risk of flooding, drought and water pollution
6.1 How has the water cycle in China changed in the past few decades
How did Evaporation, Transpiration, Interception, Infiltration, Surface runoff and Groundwater change after urban development?
6.1 How has the water cycle in China changed in the past few decades
- Evaporation: less
- Transpiration: less
- Interception: less
- Infiltration: less
- Surface runoff: more
- Groundwater: less
6.1 How has the water cycle in China changed in the past few decades
After urban development, why does the amount of Evaporation decrease?
6.1 How has the water cycle in China changed in the past few decades
The reclamation of lakes cause fewer water bodies in the city.
6.1 How has the water cycle in China changed in the past few decades
After urban development, why does Transpiration decrease?
6.1 How has the water cycle in China changed in the past few decades
tree are cut down
> reduced vegetation
> less water is transpired from vegetation
6.1 How has the water cycle in China changed in the past few decades
After urban development, why does Interception decrease?
6.1 How has the water cycle in China changed in the past few decades
reduce vegetation cover
> less rainfall is intercepted before reaching the ground
6.1 How has the water cycle in China changed in the past few decades
After urban development, why does Infiltration decrease?
6.1 How has the water cycle in China changed in the past few decades
extensive impermeable concrete surfaces
prevent water from infiltrating into ths soil
6.1 How has the water cycle in China changed in the past few decades
After urban development, why does surface runoff increase?
6.1 How has the water cycle in China changed in the past few decades
infiltration decrease
surface runoff rapidly increase during heavy rain.
6.1 How has the water cycle in China changed in the past few decades
After urban development, why does groundwater decrease?
6.1 How has the water cycle in China changed in the past few decades
infiltration decrease
groundwater cannot be recharged
