Artesian Basins and Aquifers


Explain the functioning and management of artesian basins and aquifers, distinguishing between natural and artificial recharge

 

groundwater extraction and recharge

  1. Identify and list natural and artificial methods of groundwater recharge
  2. Explain 3 ways that losses of groundwater happen
 

drainage basin processes and groundwater

 
 

ARTESIAN BASINS and AQUIFERS

The functioning and management of artesian basins and aquifers

The functioning and management of artesian basins and aquifers

  1. Draw a labelled diagram explaining how artesian basins work
 
 

case study: the great artesian basin, australia

  1. Watch the video and make notes on how aquifers work
  2. Using this information, create a diagram showing the functioning of aquifers and artesian basins
 
 

groundwater 

  1. Scan the text and highlight the word 'recharge' with one colour, all other key words with a different colour
  2. Re-read the document and explain the difference between natural and artificial recharge by adding information to two columns
  3. Summarise the environmental impacts of groundwater extraction
 
 

exam practice

(i) Briefly outline how the natural recharge of an aquifer takes place. (2 marks)

(ii) State two methods that can be used to artificially recharge an aquifer. (2 marks)

 

Mark Scheme

(i) Natural recharge happens through normal percolation after rainfall/snowfall [1] and/or a gradual seepage from rivers or other water bodies [1].

Credit any valid extension of either point or any comment that relates to the geology/porosity of rock [1] of the area that allows downward movement of water.

(ii) Through creation of recharge basin lakes [1] or water pumped down the bore hole [1]. Credit any other logical reason why more water could be introduced to a region where an aquifer is present, eg drainage diversion [1].
