  • Labelling units i.e x=width y=height
  • Use a pen to sketch the graph
  • Join the points with a smooth curve

  • HR = Cross Sectional Area/Wetted Perimeter
  • HR = Cross sectional Area X Wetted perimeter
  • HR = Wetted Perimeter/Cross Sectional Area
  • HR = Wetted Area X Cross Sectional Area X 3.147/Pi

4. Why was this method done?

  • To identify the wetted perimeter
  • To identify the cross sectional area
  • To (directly) identify the HR
  • To identify how much erosion occurred

5. Which one of the following describes stratified sampling?

  • All data has the same possibility of being chosen
  • Data divided into characteristics of choice i.e. Every blue flower
  • Data with consistent increments i.e. every 10 metres
