Answer the learning goals

• By paragraph
• In pairs
• You can use BuiteNLand

• Write down the answers to the learning goals 
• 3 minutes for each paragraph 

Learning goals §3.1

1. You know how the short and long hydrological cycles work and in which forms water is stored.
   
2. You understand why a lot of water is unsuitable or unreachable for humans.
   
3. You can distinguish areas on the map of the world which are (too) dry or (too) wet.
   

Hydrological cycle

• Short hydrological cycle
• Long hydrological cycle

Distribution of water

Accessible fresh water:

• Groundwater
• Water in the air (water vapor) 
• Water in lakes
• Water in rivers
• Water in plants

Learning goals §3.2

1. You know the meaning of all terms associated with the water balance (useful precipitation, fossil water, aquifer) and sustainable water management  (renewable and non-renewable water resources).
2. You understand how a water balance is put together.
3. You can explain the importance of sustainable water management.

An area can get water in three ways:

1. (Useful)precipitation

2. Ground- and river water

3. Fossil water (aquifer)

Water balance: Netherlands 

• Precipitation
  
• Groundwater and rivers 
• Fossil water 

• Evaporation
• Outflow into the sea
• Water for consumption

Non-renewable resources: 

it runs out

Renewable water resources:

it will not run out

Learning goals §3.3

1. You know which areas have greater flood risks (7 areas)
   
2. You understand why the flood risk of many areas is increasing.
   
3. You can assess a number of measures to reduce flood risks.
   

 

By nature:

1. River and coastal plains
2. At the foot of a mountain with a rocky surface
3. Melting snow and heavy rainfall 
4. Tropical hurricanes 

By humans:

1. Deforestation 
2. Urbanisation 
3. Areas where the ground is sinking (soil subsidence)
   

Type of areas with a high flood risk

• Extreme overstromingen door hevige neerslag 
  
• Zeespiegelstijging 
  

• Op de korte termijn
• Op de lange termijn

The number of floods                      Measures:

increases:

Learning goals §3.4

1. You know that water stress can be caused by physical water shortage and economic water scarcity.
   
2. You understand why increasing water stress could lead to a water war.
   
3. You can assess a number of measures to eliminate water shortages.
   

In the future

More water is needed:

     - increase in population

     - increase in prosperity 

     - urbanisation

Consequences:  

      - water stress

      - physical water shortage

      - economic water scarcity 

Water stress

"All the problems that arise as a result of a shortage of clean drinking water"

Two types:

1. Physical water shortage: there is too little water in an area to meet the needs of the people without disrupting the nature

2. Economic water scarcity: too little has been invested to get the available water to the people
