Slide 1 - Diapositive

What is the plan for today?

Short repeat of C2.2: Rivers of ice

THE LAST PARAGRAPH
  • C2.3: Catchment area of the Rhine

Slide 2 - Diapositive

Goals of last lesson
  1. You can explain the differences in origin between a U-shaped valley and a V-shaped
    valley
  2. You can relate the terms glacial tunnel, glacial portal and glacier-fed river to each other.
  3. You can explain how the weathered material is carried by 4 different transporters (G83).
  4. You can describe the relationship between the flow speed of the river and erosion.

C2.3: Catchment area of 
the Rhine

Slide 10 - Diapositive

Today's goals
  1. You can explain the relationship between meanders and the flow speed in the Upper Plain
    (W9, W10, G90). 
  2. You can explain in 3 steps how an oxbow lake is created (W11, G90).
  3. You can use a map to show the watershed between two catchment areas (G120).
  4. You can explain why the flow rate in summer is much lower than in winter (G120).

Slide 11 - Diapositive

Catchment area of the Rhine

Catchment area /
watershed

Try to draw a watershed from the side including
the Rhine and the Maas

Slide 12 - Diapositive

G120 in your GeoGuide
W8 in your workbook

Slide 13 - Diapositive

Upper- middle- and lower reaches

Slide 14 - Diapositive

MEANDERING (G90)

A natural bend in a river.

EROSION
SEDIMENTS

Slide 15 - Diapositive

Meander

  • On the lowlands -> low flow speed -> less erosion -> wide valley
  • Rhine will meander = make wide bends

Slide 16 - Diapositive

Slide 17 - Diapositive

Meanders are getting bigger and bigger. The water flows faster in the outer bend (erosion) and slower in the inner bend (sedimentation).

Slide 18 - Diapositive

Formation of an oxbow lake

Slide 19 - Diapositive

Open exercise 6 in your workbook

Finished? Make exercise 9

Slide 20 - Diapositive

G79: HORST &
GRABEN

Slide 21 - Diapositive

Let's go!
  • Read the text at page 28/29 of your coursebook.
  • Make exercises 1, 6, 9 of paragraph 3 in your workbook.
  • Read GeoGuide number 79 & figure 3.26
Rules while working:
  • You're allowed to work together, but whisper.
  • Raise your finger if you've a question.

Finished? Start working out the list of knowledge and skills.


Slide 22 - Diapositive

G121: Fall and gradient
Fall: The difference in altitude between two points along a river.
Gradient: The fall per kilometre.

Take question 8 in front of you

Slide 23 - Diapositive

You can calculate the fall and gradient between 2 points in a river (G121).
FALL & GRADIENT

Slide 24 - Diapositive

Today's goals
  1. You can explain the relationship between meanders and the flow speed in the Upper Plain
    (W9, W10, G90). 
  2. You can explain in 3 steps how an oxbow lake is created (W11, G90).
  3. You can use a map to show the watershed between two catchment areas (G120).
  4. You can explain why the flow rate in summer is much lower than in winter (G120).
Answer today's goals in your notebook, it's part of the homework.
