Drainage Basin Processes


Name the features of a drainage basin and explain the movement of water

 
 

Watch and note the keywords in this video

 
 
A drainage basin is an area within which water supplied by precipitation is transferred to the ocean, a lake or larger stream. It includes all the area that is drained by a river and its tributaries.
— Cambridge IGCSE Geography
 
 

Definitions

  1. Research the definitions of the following words.
  2. Annotate a simple diagram of a drainage basin with the word and definition:
  • drainage basin
  • tributary
  • confluence
  • watershed

   3. Read and make notes on p 98 IGCSE book

 
 

HYDROLOGICAL CYCLE

  1. Make a simple copy of this diagram in your notes, adding keywords, colour and a title.

TASK

  1. In pairs, complete the gap fill using the words from this diagram
  2. Stick the completed gap fill into your notes.
  3. Write a pragraph describing two different ways that water passes through the drainage basin system. Refer to the keywords throughout.
  4. Read pp 98 - 101 and make notes on the different processes using titles.

River Profile


Describe and explain the long profile and shape in cross section

Imagine you are travelling down a river, from the source in the mountains to the mouth at the sea. How would the landscape change along the way? Describe this with a neighbour.

 
 

LONG PROFILE OF RIVER

  1. Draw a simple long profile of a river on A3 paper
  2. Label your diagram with information from the resources below
  3. Add diagrams / sketches to your long profile

River Processes


Demonstrate an understanding of processes of erosion, transport and deposition.

Explain why and where in a river’s course deposition takes place.

River Processes


Demonstrate an understanding of processes of erosion, transport and deposition.

Explain why and where in a river’s course deposition takes place.

A river removes material from the sides (banks) and bottom (bed) of the river channel. This is called erosion

The boulders, pebbles, sand, silt and mud are carried downstream. This is called transportation. The material being transported is called the load.

When the river loses energy it deposits material on the river bed. The largest material (boulders) are deposited first.

  1. Copy the text above into your notes

MEmory game

You are going to watch a short video then explain it to your partner. Your partner will not see the video. This will improve your working memory, a key learning skill.

  1. Form groups of 2: Student A and Student B
  2. B students wait outside class and agree on a strategy for memory recall
  3. A students watch video River Erosion
  4. B students return to class. A students draw processes and explain to B.
  5. Repeat for River Transport video.
  6. All students watch both videos and give a score to their partner with feedback.
 

geographical diagrams

  1. Fold an A3 piece of paper 3 times
  2. Draw the 8 processes
  3. Add titles and labels explaining the processes
