Slide 4 - Tekstslide

Hydrological cycle
  • Short hydrological cycle
  • Long hydrological cycle

Slide 5 - Tekstslide

Distribution of water
Accessible fresh water:

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

Slide 6 - Tekstslide

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.

Slide 7 - Tekstslide

An area can get water in three ways:


1. (Useful)precipitation
2. Ground- and river water
3. Fossil water (aquifer)

Slide 8 - Tekstslide

Water balance: Netherlands 
  • Precipitation
  • Groundwater and rivers 
  • Fossil water 


  • Evaporation
  • Outflow into the sea
  • Water for consumption

Slide 9 - Tekstslide

Non-renewable resources: 
it runs out
Renewable water resources:
it will not run out

Slide 10 - Tekstslide

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.

Slide 11 - Tekstslide



 
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

Slide 12 - Tekstslide




  • Extreme overstromingen door hevige neerslag 
  • Zeespiegelstijging 



  • Op de korte termijn
  • Op de lange termijn
The number of floods                      Measures:
increases:

Slide 13 - Tekstslide

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.

Slide 14 - Tekstslide

In the future
More water is needed:
     - increase in population
     - increase in prosperity 
     - urbanisation
Consequences:  
      - water stress
      - physical water shortage
      - economic water scarcity 

Slide 15 - Tekstslide

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

Slide 16 - Tekstslide
