2.3: catchment area of the Rhine
- repeating meanders, oxbow lakes, upper- middle- and lower course
- Explanation and quiz questions about: Gradient and fall, horsts and graben, flow rate
- Answer questions: 2, 5, 8, 9 (homework)

#### Slide 1 -Tekstslide

What is sediment?
Give 3 examples

#### Slide 2 -Open vraag

Upper reaches
Middle reaches
Lower reaches
Here is the source of the river
Water flows slowly
Here is the river mouth
Rivier takes as much material as it leaves
This is where the river meanders

#### Slide 3 -Sleepvraag

Horsts and Graben
Graben = when a part of the land is sinking in the earth
Horsts: the parts of land next to a Graben. These parts stay high

#### Slide 4 -Tekstslide

Sleep de begrippen naar de juiste plek.

#### Slide 6 -Sleepvraag

Watch the video on the next slide
1. How does the landscape change from Rotterdam to Basel when a ship follows the Rhine?

#### Slide 8 -Video

Fall and gradient of a river
Upper course
Fast flow - steep river -large gradient
Lower course:
Slow flow - gentle slope - small gradient

Fall = difference in height between 2 places in the river

#### Slide 9 -Tekstslide

The fall is highest here
The fall is smallest here

#### Slide 11 -Tekstslide

A lot of erosion
Flows slowly
Wide valley
Flows fast
A lot of sedimentation

#### Slide 12 -Sleepvraag

Q. 8
Calculate fall
Altitude A - altitude B

Fall / length of the river AB

#### Slide 13 -Tekstslide

Q. 8
Calculate fall
2500m (alt. A) - 1500 (alt.B)
= 1000 m
1000m (fall) / 250 km (length AB)
1000/250=4 m/km of river

#### Slide 14 -Tekstslide

Fall
The height difference between 2 places in the river.
The average height difference per kilomter of river

#### Slide 15 -Sleepvraag

River regime
= The pattern of how much water is flowing through the river throughout the year

#### Slide 17 -Tekstslide

IIn these graphs you see the regime of 3 rivers. Decide for each graph what kind of river flows through there.
Glacier-fed river
Rain-fed river (seaclimate)
Rain-fed river (tropical climate)
