Chapter 3: paragraph 4

• Aardrijkskunde
• Middelbare school
• vwo
• Leerjaar 2

What do you know at the end of the lesson?

1. How climate change influences precipitation
2. How characteristics of precipitation have changed
3. The measures included in the project 'room for the river'

Language aims: 

You are able to use the words flow rate and regime to explain the effect of climate change.

You are able to use the words: precipitation, water vapour, evaporation, acummulation (water storage), condensation, long watercycle and short watercycle in a small story.

Par. 4: Taming rivers

In which year would you place this picture?

There it is again: the watercycle!

Take your notebook and draw along!
Use the terms used in the song.

You can explain how climate change influences the amount of precipitation.

Climate change

• Warmer = more water vapour above sea =
  more moist air above land
• More rain instead of snow
• Heavy downpours, especially in summer

Rivers

What if suddenly a lot of rain falls and a lot of snow melts?

TAMING THE RIVERS!!

REGIME

Fluctuations in a river's flow rate in a year.

FLOW RATE

The amount of water flowing at a particular point in the river (expressed in m3/sec).

The effect of more precipitation and snow melting

WATER MEASURES

A couple of water measures

Lowering the groynes(kribben)

Secondary channel- (nevengeul)

Lowering FLOODPLAINS

Area between dikes and the river bed.

Done? Start working on exercise 1 to 4 and the lessonup questions 

Or, if you like a challenge do exercise 12 instead+ lessonup questions

Work on exercise 5

Room for river measures

Precipitation is affected by climate change. Why is this worrying us?

How is the regime of a river affected by climate change

Include a picture of a water measure

Now you know
