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.

the Rhine

Slide 13 - Slide

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).

Upper- middle- and lower reaches

Slide 17 - Slide

MEANDERING (G90)

A natural bend in a river.

EROSION
SEDIMENTS

Slide 18 - Slide

Meander

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

Slide 19 - Slide

Slide 20 - Slide

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

Slide 21 - Slide

Formation of an oxbow lake

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 25 - Slide

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 26 - Slide

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