AS A Level Geography Quiz: Storm Hydrographs

1. Which of the following affects the shape of a storm hydrograph?

Channel size

River stage

Rock type

Meanders

2. Which statement correctly describes what a rising limp is?

It occurs once to discharge during the rain season

There is no such thing

It shows increasing river discharge after a rain/precipitation event in the basin

It is the tributary with the highest discharge in the drainage basin

It’s the highest discharge reached by a river after a rain/precipitation event in the basin

3. How does urbanisation affect the shape of a hydrograph? Choose all the right answers.

Longer peak discharge

Higher peak discharge

Longer lag time

Steeper rising limb

Rising limb becomes less steep

Lower peak discharge

Shorter discharge

4. Which of the following does not affect the shape of a storm hydrograph?

Vegetation type

Drainage density

Drainage pattern

Slope

5. What is peak flow as shown on a storm hydrograph?

It is the lowest flow after or before a rain event

It is the highest flow after a precipitation event in the river channel

It is the lowest flow the river reaches each season

It’s the highest discharge a river reaches each season

6. Which statement correctly describes the recession limb?

It happens twice after each rain event

None of the above

It is when the river recedes upstream after a rain/precipitation event

It is when the river’s discharge falls after reaching a peak discharge

7. What is a storm hydrograph? Select all the correct answers

It calculates lag time

It is built across a river channel to measure storm discharge

It measures peak discharge in metres per second

It is different from a flood hydrograph

8. Which land uses affects the shape of a storm hydrograph? Select all the right answers.

Deforestation

Reafforestation

Urbanisation

Farming

9. Which is true about storm hydrographs?

They have to be constructed for each rain event

They are not really useful to humans

They only ever need to be constructed once each season

They are all computer-generated animations

10. Which is not true about storm hydrographs?

They are also known as flood hydrographs

They show river discharge for the entire rain season

They show lag time after an event before peak discharge is reached

They show changes in discharge over time
