• Aardrijkskunde
• Middelbare school
• vwo
• Leerjaar 2

At the end of this lesson you will know:

• why there is always a risk of flooding
• how the Netherlands protects itself against water
  
• why the sea level is rising
• why the ground in the Netherlands is sinking
• 
  
• Language aim: 
• You can explain the definition of relative sea-level rise.
• You are able to explain the word subsidence
• You are able to explain why the netherlands is on a seesaw since last ice age.
  
  

Below sea level

Flood risk in the Netherlands from

- the sea = large part of the country is below sea level

- rivers

The Netherlands is protected by dikes and dunes

The Low Netherlands consists of polders: areas where the water level is controlled using man-made methods.

Water boards (waterschap) have 3 tasks:

- water safety

- water purification

- water management (enough fresh water)

You know 3 reasons for subsidence in the Netherlands.

1. "Seesaw" (wip) after the last ice age.
2. Pumping away rising groundwater.
3. The extraction of "minerals".

SUBSIDENCE = verzakking

during/after the last ice age

As scandinavia is on the other side of the seesaw.

Causes of subsidence

What are the causes of subsidence?

1.In the last ice age > thick layer of ice pushed down the Earth’s crust > ice disappeared, ground in Scandinavia ‘sprang’ back again> ground in the north of the Netherlands sank

2.Pumping away groundwater in the Low Netherlands >the ground sinks > worst in peatlands

3.Due to extraction of natural resources > natural gas in Groningen

You can explain the definition of relative sea-level rise.

Assignment

Write a summary about the relative sea-level rising. 

Why is it happening?

Use the words: subsidence, seesaw, relative sea-level rising, glacier.

At the end of this lesson you will know:

• Which area would flood without dikes and dunes
• How is sand suppletion used to strenghten the coast?

• You can explain what sand suppletion is

NETHERLANDS BELOW SEALEVEL

WATER MEASURES- maatregelen

Sandsuppletion-Putting a lot of extra sand along the coast to protect against rising sea levels.

Assignment

What: List all water measures that have been taken troughout the Netherlands.

How: find it in the book, read it from the maps, find it on google if you like

Time: take 10 minutes to do this.

Finished? Start working on exercise 9 and 10 by using the atlas. When those are done you may work on exercise 7 and 8.
Finished with that......start working on your sustainable island

Now you know:

• Which area would flood without dikes and dunes
• How sand suppletion is used to strenghten the coast

Language aim:

• You are able to explain what water measures are
• You can explain what sand suppletion is
