Presentation Transcript

  1. Data Presentation

  2. What the mark scheme says:

  3. Section A - Channel Shape

  4. Width 1cm = 1m 0 1m 2m 0 10 20 Depth 1cm = 10 cm 30 Scale: Depth: 1cm =10 cm Width: 1cm = 1m 1.Channel shape graph for the Lower Course (site 1)

  5. 2. Bar graph showing average width of the Glenarm river at the Lower, Middle, Upper course (Sites 1,2,3) (You must convert all your depth measurements into meters. i.e they will be 0.56m etc) River Width Depth data.xls

  6. Section B -River speed / velocity

  7. 1. Velocity across the channel To calculate velocity you must remember to: Distance ÷ time = velocity 10 ÷ average time in seconds = m/ seconds

  8. Line graph to show the changes in the velocity across the channel in the Lower course (Site 1) (X3 graphs for each site)

  9. Bar graph to compare the average velocity between the Lower, Middle, Upper course (Site 1,2, 3) 2. Average Velocity comparison graph

  10. Section C - Bedlaod

  11. 1. Av Bedload shape 5 = very angular 4= angular 3= sub-angular 2= rounded 1= well rounded

  12. 2. Av Bedload size

  13. 3. Relationship between bedload size and shape Scatter Graph to show the relationship between bedload size and bedload shape for the Lower, Middle, Upper course (Sites 1,2,3)
