Geography flooding quiz

Select all the natural causes of flooding

• Deforestation

• Precipitation

• Geology

• New houses and cities

What is this?

• The Bradshaw model

• River long profile

• River Cross section

• I don’t know, something about triangles

What factors could decrease the risk of flooding here?

• Impermeable rock because it can absorb more water

• Dry soil because it can hold more discharge decreasing surface run off

• Woodland because trees can store water decreasing surface storage
