Development leading to increased flooding Flashcards
1
Q
landuse changes, overgrazing and clear felling can lead to…
A
DEFORESTATION
2
Q
problems of deforestation
A
-reduces interception and evapotranspiration by plants
3
Q
how does reducing interception and evapotranspiration lead to increased risk of flooding?
A
increases runoff leading to higher peak flow
4
Q
urban development includes
A
- floodplain encroachment
- impermeable urban land
- efficient drainage networks
5
Q
how does floodplain enrichment lead to increased risk of flooding?
A
loss of floodplain wetland and storage due to levee construction to protect floodplain development=more rapid ruoff
6
Q
how does impermeable urban land lead to increased risk of flooding?
A
less storage and less transpiratio
