How do changes in how water moves through the hydrological
cycle affect the risk of flooding?
Starter: Without looking back at your notes, write down as many parts
of the Hydrological Cycle as possible.
Those who missed last week – grab a revision sheet from me.

2. Pass Remember the key terms of the
hydrological cycle and use them to
explain flood risk.
Higher Able to suggest reasons why the River
Adur floods and apply your knowledge
to an unknown river with a basic answer.
Star Able to apply your knowledge of the
hydrological cycle to an
unknown river with a developed
answer.

3. • Precipitation
• Groundwater Flow
• Groundwater
• Soil Moisture
• Evaporation
• River Flow
• Surface Runoff
• Interception
• Transpiration
• Infiltration
• Throughflow
• Percolation

4. Hydrological cycle Pictionary
• Teams of 3.
• One person comes to
me for a term.
• Return to team and
draw.

5. Keywords check
• What is………….
1. Percolation?
2. Groundwater flow?
3. Throughflow?
4. Surface run-off?
5. Transpiration?
6. Evaporation?
7. Condensation?
8. Infiltration?
9. Channel flow?
10. Saturated?
• Answers:
1. Water soaking into bedrock
2. Water flowing through bedrock
3. Water flowing through soils
4. Water flowing over soil (doesn’t soak in)
5. Water ‘breathed out’ by plants
6. Water liquid turning into vapour
7. Water cooling and returning to liquid
8. Water soaking in to soils
9. Water flowing in a river/stream
10. When soil/rock is full of water and no more
can infiltrate

6. Big Picture
How water flows around a river system and
affects flooding.
The main features of a drainage basin.
A case study of flooding.
A case study of how a river is managed.

8. Other than extreme flooding, suggest one reason why the River
Adur floods. (3)
Use the hydrological cycle to list as many reasons as possible
(there are 5)
River Adur is a main case study – features,
flooding, management.

9. What factors affect the flow of water through the hydrological cycle?
How to write an extended answer.
so that
means
that
How
hydrological
cycle is
affected
Factor
Result on
flooding
so that
means
that

10. What factors affect the flow of water through the hydrological cycle?
Land-use
Weather
Geology
Relief
How hydrological cycle
means that so that
Factor is affected Result on flooding

11. On your sheet:
1. Select a Pass or Higher list of factors
2. Sort each factor into the correct part of
the diagram.
3. Create a ‘means that’ ‘so that’
explanation.

13. Other than extreme flooding, suggest one reason why the River
Adur floods. (3)
Use the hydrological cycle to list as many reasons as possible
(there are 5)
River Adur is a main case study – features,
flooding, management.
