O-LevelGeographyThe natural environmentMay/June 2010Paper 2 Q830 Marks
Some students wanted to investigate the flow of a river on a meander. Before they began their fieldwork their teacher spoke to them about safety when planning their fieldwork. The students decided to investigate two hypotheses about the speed of flow (velocity) of the water in the river: Hypothesis 1: Velocity on the surface varies across a river meander. Hypothesis 2: Velocity is greater on the surface and decreases as the depth of the channel increases.
