#### Slide 3 -Tekstslide

C2.3: Catchment area of
the Rhine

#### Slide 4 -Tekstslide

Goals of last lesson
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).

Today's goals
1. You can link the characteristics flow speed, fall, erosion, sedimentation, to the upper,
middle and lower reaches of a river (W8).
2. You can explain the origin of the horsts and grabens.
3. You can calculate the fall and gradient between 2 points in a river (G121).
4. You can explain the difference in formation between an estuary and a delta, using the
terms sedimentation and erosion (G90).

Let's go!
• Make exercises 7, 8, 9 + W14 of paragraph 3 in your workbook.
Rules while working:
• You work alone and in silence.
• Raise your finger if you've a question.
