1 A group of students was collecting data along the length of a river as
part of an investigation into changes in a river channel.
(a) The students had planned to use a flow meter to measure the velocity of
the river, but one of their chosen sites was too shallow.
State one way they could adapt their technique. (1)
(b) Give one piece of equipment, other than a flow meter, they would
need to use to investigate river discharge. (1)
Study Figure 1a in the Resource Booklet. It shows a sketch of sites used to collect
river data.
(c) Explain one reason why the students chose a stratified sampling approach. (3)
2
,Study Figure 1b in the Resource Booklet.
(di) Which of the following are the correct units used for cross-sectional area in
Figure 1b. (1)
(dii) Calculate the mean and median depth of the river. (2)
(diii) Using Figure 1b, explain one reason why a student might choose to use the
results from the median, rather than the mean. (2)

, or (Coasts)
2 A group of students were collecting data along the length of a coast as
part of an investigation into coastal processes.
(a) The students had planned to use a tape measure to measure the width of the
beach, but the weather was very windy.
State one way they could adapt their technique. (1)
(b) Give one piece of equipment, other than a tape measure, they would
need to use to investigate beach gradient. (1)
Study Figure 2a in the Resource Booklet. It shows a sketch of sites used to collect
coastal data.
