River Fieldwork

You will prove or disprove the following hypothesis:

• Stream Velocity Increases with Distance from the Source.
• Stream Discharge Increases with Distance from the Source.

Complete the following steps to help you prove or disprove the hypothesis:

1. Download each of the Excel documents - one for each of the fieldwork sites.
2. Complete the necessary calculations for each fieldwork site - some of the infomation can be found by clicking on the site locations on the map.
3. Produce a table in Excel that shows distance from source, velocity, discharge and hydraulic radius for each site.
4. Produce a graph to show how velocity changes with distance from the source - be careful with your x axis (distance from source).
5. Produce a graph to show how discharge changes with distance from the source - be careful with your x axis (distance from source).
6. Write a conclusion - how and why do your graphs prove or disprove the two hypotheses.
7. Extension Task: Produce a graph to show how hydraulic radius changes with distance from the source. Explain your findings.
