Some students were studying how the characteristics of a river change downstream. They decided to focus their fieldwork investigation on a local river to see if it had some characteristics of a text book example. These characteristics are shown in Fig. 8 (Insert). The students agreed to investigate two hypotheses: Hypothesis 1: The width, depth and cross-sectional area of the river increase downstream. Hypothesis 2: Velocity is greater where the river is deeper.
