June 07
a) In relation to river studies what is meant by a ‘knick point’
(2 marks)
b) Describe and suggest reasons for the variations in valley long profiles.
(8 marks)
c) Draw and label two valley cross profiles found along the course of a river, for one of these profiles,
explain how processes of river erosion have contributed to its formation
(6 marks)

1. a) Study Figure 1, which shows part of a drainage basin in an upland area underlain by impermeable
rock. Suggest why this area would produce a flashy hydrograph following a storm event. (6 marks)
b) Study Figure 2, which shows the monthly variations in maximum and mean discharge for a river
draining an upland catchment. Describe the variations and suggest why this catchment might cause
problems for river management.
(6 marks)
c) Study Figure 3 which shows some methods that have been applied to channels and catchments in an
attempt to manage river flow. Suggest how two of these methods would influence the risk of flooding.
(5 marks)
June 06
a) What is meant by the term infiltration in relation to drainage basin hydrology (2 marks)
b) Give two factors that influence the rate of infiltration (2 marks)
Jan 06
a) In the context of river studies what is meant by a ‘graded profile’.
(2 marks)
b) Describe and suggest reasons for the development of knick points and waterfalls in valley long
profiles.
(10 marks)
c) Human activity can influence the shape of the storm hydrograph. Choose one type of landuse change
and suggest how that change would modify the storm hydrograph.
(5 marks)
Jan 05
a) For a river that drains a catchment area underlain by impermeable rock, draw a fully labelled diagram
to show the shape of the hydrograph that would be produced as a result of a rainstorm following a
period of prolonged wet weather. (5 marks)
June 05
a) What is meant by abrasion and attrition in relation to rivers
(4 marks)
b) How do variations in velocity influence a river’s ability to pick up and transport material
(6 marks)
Explain with the aid of a diagram, how processes of erosion and deposition affect the cross-section of a
river channel.
(7 marks)
Jan 04
a) What is meant by the term abrasion in relation to river studies
(2 marks)
b) Describe how variations in velocity affect the ability of a river to pick up and transport material (5
marks)
c) With the aid of a diagram, show how the processes of erosion and deposition influence the shape of
the channel

January 2001
(a) For a river that drains a catchment area underlain by impermeable rock, draw and label a typical storm
hydrograph, which would be produced as a result of a rainstorm following a period of predominantly wet
weather. (4 marks)
(b) Suggest reasons for the shape of the Hydrograph. (4 marks)
