This section refers back to sections E – G in the wiki
There is a presentation that summarizes the data:Drainage systems U2 Drainage patterns and drainage density
- Activity 1
Study the relevant section in the Wiki and on the video and then make a table for your study purposes that summarises the seven drainage patterns . The first row of the table is given below as an example:
DRAINAGE PATTERN
ACTIVITY 2
Study the relevant section in the wiki then respond to the case below:
A farmer has a large farm measuring 6,4 sq. km. but he is concerned that he may not always have enough water for his crops. He decides first to work out how quickly water drains off his property. The farm has 8 different streams crossing it and their total length is 12, 8 km. Previously most of the farm was used for growing pineapples, but he is keen to use it as pasture for cattle and to grow a mixture of lucerne, maize and oats.
What is the drainage density of his farm?
Is there anything he can do to retain more underground water and reduce the amount that is drained away?
