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 - Slide

What is sediment?
Give 3 examples

Slide 2 - Open question

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 - Drag question

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 - Slide

  1. How does the landscape change from Rotterdam to Basel when a ship follows the Rhine?

Slide 7 - Slide

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
Gradient = fall per kilometer

Slide 9 - Slide

The fall is highest here
The fall is smallest here
The gradient is lowest here

Slide 10 - Drag question

Slide 11 - Slide

A lot of erosion
Flows slowly
Wide valley
Flows fast
Small gradient
Large gradient
A lot of sedimentation

Slide 12 - Drag question

Q. 8
Calculate fall
Altitude A - altitude B

Calculate gradient
Fall / length of the river AB

Gradient = ... m/km

Slide 13 - Slide

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

Slide 14 - Slide

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

Slide 15 - Drag question

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

Slide 16 - Slide

Slide 17 - Slide

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)
