Study Figure 9, which are photographs of the two access points chosen by a group of students studying river channel changes on a river at two different locations.
- The students chose to measure river channels at two different locations.
- The chosen locations are about 10 km apart with Location A furthest upstream and Location B furthest downstream.
- At each location they selected three sites to carry out their channel measurements.
- They intended to measure channel width and channel depth.

i)
Suggest an enquiry question or hypothesis that the students might have proposed for their investigation.
(2)
ii)
Suggest two problems that the students’ choice of locations may have caused for data collection.
(4)
iii)
Explain how the use of Ordnance Survey (OS) maps might have helped the students choose their two river locations and the three sites on each of those rivers to carry out their channel measurements.
