8. - The course
 We can
Distinguish 3 - The flow
elements in
a river - The flow regime

9.  The course of a river is the route which a river

This is
the
source of
the river
This is
the
mouth of
the river
This is the
COURSE of
the river

10.  There are
3 courses:
Upper course
Middle course
Lower course

11.  It is near the source.
Here, the river is narrow.
The river bed is steep, so the water moves fast.

12.  Here, the river is wider. The river bed is flatter,
so the water flows slowly.

13.  In the middle course, the river forms
curves. These curves are called
meanderings.
This is a
meandering

14.  It is near the mouth of the river.
The river is wide here. The river bed is very flat,
so the water moves very slowly.

15. What is the flow of a river?

carries.
The more precipitacion there is, the greater the
flow will be.

flow.

It is the most
plentiful river of
Mediterranean

 In the summer they carry less water.
