Step 3 - Presenting & Organising Your Data...
Word Count - 0 (just graphs, annotated maps, annotated photos and charts)

Top Tip: Once you have all of your annotated photos, graphs and charts, mix them in to the Step 4 work to make it one big chapter. Don't block all the data presentation together. It makes it really difficult for the examiner to make sense of.

The data presentation refers to any graphs, charts or annotated photos you include. It's where you show the relationships that help to prove or disprove your hypotheses.
Task 1 - Use a Google Map of the River Aussonnelle (showing 6 study sites) to create an information page to show the main features of each of the 6 study locations. You can use this template if you want. You might want to think about.....
a. How wide or narrow the channel is.
b. How steep the banks are.
c. If there has been any modification to the channel by people.
d. Surrounding vegetation.
e. If there was a tributary.
f. Any evidence of erosion or deposition.
Task 2 - You will need to process the data that you collected from the methods that you will need. The data presentation from this data are likely to include:
a. Scatter graphs with lines of best fit (to show relationships) and standard deviation - good for velocity & sediment size.
b. Line graphs to show discharge (discharge = velocity x area). (Page 59 of this link) Don't forget, the x-axis should be distance from source in metres.
c. Bar charts to show average depth at each of the study sites (add up all depth figures for each team at each site and then divide by total number of measurements).
d. Cross sections of the river plotted from the data you collected. (Page 59 of this link). These could be presented on top of a base map (your teacher will show you an example).
e. Field sketches from selected locations (Page 58 of the link above).
f. Annotated photos to show characteristics of different study sites. e.g. to help show the differences in width of channel, velocity, human impact on the river etc.
Don't forget - You can look for relationships and plot two sets of data on the same graph. An example would be is there any relationship between average velocity and sediment size?
