Goals

By the end of the lesson, you will know: 

• Why the river area must adapt to the changing climate

• What measures are in the Room for the River plan;

• Why the Netherlands need to store water in the deltas of Sealand and South Holland during heavy rainfall;

Prior knowledge

You know why rivers may experience additional water discharge due to climate change
You know the names and location of the rivers we have in the Netherlands

De belangrijkste rivieren zijn de Rijn en de Maas.

The drain of Europe

• Netherlands is located in a delta
• Vulnerable for water

When there falls a lot of rain in Germany we will notice it in the Netherlands

What happened in 2021?

• Water discharge varies by river and is not the same throughout the year.
• The fluctuations in a river’s flow rate = regime
• Amount of water flowing at a particular point = flow rate
• In this situation the flow rate and regime were both really high
  

Climate adaptation

= adjust and design the landscape to deal with the effects of climate change 

Draw the river on the board

Room for the river

After 1995, new plan to give rivers more space

Room for the river = Government programme in the Netherlands that aimed to improve flood management and safety around major Dutch rivers.
