Question 1

how does impermeable rock factor into the risk of flooding

Answer 1

Some rock is impermeable and so the rain can’t soak into it. Instead it runs straight into the river.

Question 2

how do tributaries effect the risk of flooding

Answer 2

Where rivers join there is a greater chance of flooding because of all of the extra water.

Question 3

how does a loss of trees effect flooding

Answer 3

Trees soak up water and catch water in their leaves (interception). If we cut them down there is more chance of flooding.

Question 4

how does a flat floodplain effect flooding

Answer 4

The floodplain is flat land around the river that floods when the river gets too full – Don’t live on a floodplain!

Question 5

how does heavy rainfall effect flooding

Answer 5

Heavy rain is the main cause of flooding

Question 6

how does soggy soil effect flooding

Answer 6

If there has been a lot of rain lately, the soil will be soggy already. When more rain arrives it won’t be able to soak into the soil.

Question 7

how does built up areas effect flooding

Answer 7

Rain can’t soak through concrete, therefore the water will run off straight into the river.
